- The second part of hacking a hoverboard motherboard, in this video i show you which wires to connect to what to make the motors move how you want,
I cant put the code here so i will put it in a comment for you
make sure you also get the Adafruit_MCP4725 and WIRE libraries or it wont work, feel free to ask questions in the comments

A-Tech Hello Sir. First of all It’s a great Job. Very clear video. I have only one question why reverse is so slow and is there any why to increase it? Thank you so much.
@@zeko120 hi, im not too sure whats going on with the reverse, as soon as i know and get it sorted i will share it, thanks
@@A-tech Hello master!
I looked at two parts of your video yesterday, and today I redone the gyroscooter with the firmware presented.
As a result, it sometimes does not work stably with potentiometers, and as already noted, the use of DAC is required.
I will also note a slow and insecure reverse. But he definitely is:)
If you 're a firmware author for stm32, I have a question:
Is there any firmware for implementation of the three H-bridge for brushed dc motor throught one hoverboard mainboard?
I 'll follow the project closely!
Certainly a great job has been done!
@@igormorozov6801 Hi yes DAC does make it a lot better, the reverse is really slow i know, i havnt been able to fix that yet.
i like your idea for controlling dc motors with the mainboard but im not sure if its possible.
Thanks for your nice comments its very motivating to hear them, thanks
@@A-tech hi, thank you so Much! i'm making a motorized chair for my dad! I really liked the project! does this code work to control the wheels correct? can you make available the last code you used to test here? Thank you again.
This is awesome!! Just followed your guide and I now have it running on an old amp volume knob and two makita batteries. I am hoping to use this to drive a small milling machine I have. Can't wait to test it in a woods somewhere. Thanks Bud.
Hi could you please make a more detailed video on how to connect the Arduino to the mother board and how to use ps3 controller to control the motors. Also can this work with Arduino uno?
Thanks for the tutorial. I have a question, it goes so much slower in reverse and the torque drops significantly. Is there a way to solve this, so that it has the same power forvard and reverse.
hi, there is a way, but im not sure how to do it, thanks
outstanding work and video!
every viewer of it should light a candle in a church for stm32 firmware programmer health and his long years living.
Yes pls make more vids on this with different sensors and joystick and PlayStation controller Thanks for this!
ok great they will be out soon, thanks
Hi i got a question i saw on auctions there exist 2 diffrent pcb boards green and dark blue of that board with one is better or newest?
Good video! Thanks. What about a video controlling the motors with a Bluetooth connection via Arduino and app inventor? 🤩
I Solved it! thanks! now I am into the nunchuck control now!
hi, i looked into it, it might be easier using an esp32, they have bluetooth and built in DAC
Can you help me? What pins do I have to solder on the Digital-to-analog converter to change its address of it? I found 8 pins on it but I don't know which one is the right one. I'd be really happy if you would take a moment to help me :D
(It was said in 10:56)
hi, oh ye the very very very important thing, if i remember correctly the pins are already soldered together and you need to get a stanley blade or something to cut the link, i think, thanks
@@A-tech Oh thank you a lot!!
This is great, I did exactly the same as you and it works like a charm :) thanks
Great to hear!
It dosnt work with me
I dont know why
With out ardiiuno
Simple alternative with esp32 using esp32's own dac, without using mcp4725, pins in esp32 -> 25 and 26.
CODE:
#include
#define DAC1 25
#define DAC2 26
void setup() {
Serial.begin(115200);
}
void loop() { // Generate a Sine wave
int Value = 130; //255= 3.3V 128=1.65V
this value change to speed
int Value2 = 150; //255= 3.3V 128=1.65V
this value turn left or right
dacWrite(DAC1, Value);
dacWrite(DAC2, Value2);
delay(1000);
}
esp32 has 2 built in DAC??
@@A-tech Yes ESP 32 has two 8 bit DAC...
I tried the above code it works..
@@A-tech that's right friend, it is a method that makes things a little easier, thanks for inspiring me
Thank you for your video
Thank you for this awesome content
This has to be the best tutorials for hacking hoverboard firmware, am using this, just one question, do you think you could hook up rc equipment directly?
Thanks so much for these two videos
hi, thanks that means a lot, apparently they can but i think you need to edit the firmware file to enable it but not 100%, if you need to use rc stuff i know you can run that through an arduino if that helps, thanks
gracias, buen trabajo.
no tengo mucha experiencia en arduino y solo intento colocar un joystick, agradezco su ayuda. abrazo!
ok, do you mean a 2 axis analogue joystick? because they self center you would need to map the values or maby use some resistors somehow, hope this helps
@@A-tech yes 2 axis analogue joystick..
voy a intentar map para controlar forward and reverse.
ok i think you will need to use an arduino, hope this helps
Great video
hi what values do the potentiometer need to be?
10k, thanks
I'd love to see how you make it work with other things like RC controller's, I'm thinking about making a electric skate board out of a hover board.
hi, im planning on a part 3 version to show other controllers, they do make good skateboards because the wheels are so big, they go over cobbled streets and bumpy tiles no problem, thanks
Hi, looking for an idea on what might be wrong, flashed the firmware from the link in the first video and all is good, no errors, but when I turn the board on with everything connected, it will slowly rotate the motor clockwise a couple times, stop and do the same counterclockwise, stop and the board turns off. All by itself. Pots have no effect whatsoever. It will do this with or without any pots connected to input wires. Im using the 3.3v pin for them. I flashed the board again, no change, everything was done to the letter from the first vid.
Halp?
ok not sure if you have sorted this now, what firmware you are using is the wrong one and just does test mode, you may be able to change it but i think there are lots of different versions
Could i replace the potentiometer with a thumb throttle? I just want to make a drift trike but im getting confused.
And, do i need the steering potentiometer? I want both wheels to always to rotate the opposite direction same speed to be like my rear axle.
i dont see why not
Please bear with me because I am a beginner, but I have a few questions. I see you are using two break out boards, one for each potentiometer. If I’m wiring two motors to one joystick do I need 4 breakout boards or just 2? It seems to me like I would need 4
After rewatching this video I now believe I understand that 2 of the breakout boards can power the analog joystick controlling 2 motors. I would love to see a video of this if you have time. I know it’s basic I just want to make sure I’m understating it thoroughly
@@LifewithLewy hi, yes you would only need 2 of them, one for each wheel, but they dont control each wheel, one does the overall speed for both and the other adjusts the difference between the 2 motors, hope this helps, thanks
A-Tech thanks for the clarification! Thats what I assumed after i rewatched it. If you get a chance to make a video I would love to see it.
I would like to see a wireless joycon (hat thingy). The idea is to make it work with a wii controller
When I turn on the motors and start to control them the board makes beeping noises and turns off by itself. Do you have any idea what might be causing it?
could be low power possibly?
where did you get the motor mounts?
they are just 16mm shaft support brackets
Is it possible to bypass the steering pot and just have the wheels spin the same speed always?
I just want throttle and break controll none of the other stuff is needed for my current project.
hi, yes you just leave the steering pot in the middle, thanks
Thank you so much for the great video. Do I have to make any code changes to connect an RC receiver to the arduino?Also, which arduino pin should be connected to RX signal wire? If you could reply to this, that would be of really great help. Thank You in advance
hi, yes you will need to make some alterations to the outputs, instead of writing to the DAC you need to write like you would to a servo, then an rc transmitter should be fine, i wasnt using an rx wire in my setup, i think thats only if you are using serial communication, thanks
hello i have question i dont have a green wire i have i white 1 what to do do i use the white one?
hi, is this for the sensor cable? so there should be red, black, blue and green, for yours you have red, black blue and white? thanks
Hello, I'm a bit late. Anyways, I want to build a go kart with an old overboard thus I don't need the steer on the rear wheels,if I just leave the steer wires unplugged will the motors just steer in one direction or will they have equal speed(remaining locked in "forward mode with no steering")?
By the way, your channel is so underrated
hi, if you dont need steering i recommend the 'bobby car' version of the firmware, this makes the wheels go the same speed and has 2 throttles, one for brakes and one for speed, it also has different running modes, so you can have a fast mode which is about 20mph, on my video where i convert a mobility scooter into a go kart this uses the bobby car firmware, hope this helps, and thanks!
@@A-tech thanks
amigo,onde consigo esse firmeware , vc tem um link ?
Can 50k potentiometer work for this process??
im not too sure, probably not
A question: Why not map potentiometer input directly to dac output? (i.e. map(pot1, 1024,0,0,4095);) It would give you much greater resolution.
hi, yes i see what you mean, i didnt notice that, thanks
Can You help me something, looks like You've studied the board. Where is located the switch or the jumper or the wire for "locking" the 2 wheels, to turn synchronized? To control both from one control?
Thanks!
hi, haha if it was that easy, im not sure if thats even possible with both the wheels being sensored, you can control them both together, with the 2x potentiometer method one does the speed and the other is balance between the 2 motors
my hoverboard each side single bldc moter how to control with potentiometer which software i can use please guide
hi, is it the same motherboard as the one in the video?
Say if I want one of the pentiometers to be a foot pedal, it has the three wires but the only thing is it says 12 to 48v, will I be able to use it
PLEASE RESPOND!!
hmm, its hard to say, if you get this working with a potentiometer then swap the potentiometer for the pedal and see if it works, there will be only low voltage going through the potentiometer
@@A-tech I thought 1 pentiometer and 1 pedal I also ordered the reprograming thingi
ok great good luck
Bro you are awesome! You don’t know how much your videos are helping me! Btw.. damn you got fast shipping on those break out boards 😂
good to know they help, ye haha
Very good, it is possible to turn left or right using this arduino code
thanks and good video
Yes, you can
Nice work, I've done this to my motherboard, but i conected only one motor, and tested it. It was fine until i sensed some heat coming from the wires of the motor phases, and also motor sounded like something was cracking. Can you asume what might be wrong?
hmm, it could be a broken wire that is not always connected? its hard to say, you may be able to test different parts with a meter to pinpoint the issue, thanks
Can we implement dual functionality, like use hoverboard as a hoverboard along with a physical controller? If yes could you please let me know.
hi, i dont see why not but you would need to set up a balance sensor and an arduino or something similar, thanks
Thank you for great video! Can it be used for simulator steering wheel force feedback?
hi, thats a cool idea, they are pretty powerful so probably, just a bit big in size
Anyone know if it might be possible to combine the output into one larger motor instead of two? If you could also keep the self balancing circuit intact it might be the start of a cheap DIY electric unicycle build?
hey, i am building a diy onewheel by combining 2 hoverboard motors, have you tried building a unicycle? Sounds like an interesting project
Thank you very much for this share
Can you please send the hex code as I could flash using the st link
I am not able to do that
Hey..Nice job.i had a question..if i want to connect a ethrottle on a hoverboard.i only want it to go forward.the throttle has 3wires.thank you john
hi, i think you would connect it up the same way as a potentiometer, you may need to adjust it somehow so it can stay in the middle, hope this helps
@@A-tech or you could put an arduino ( maybe pro micro, it's very small ) and use it to map the ethrottle using an ADC like in the video.
can i use throttle insted of potentiometer Please answer
i think you can yes but i have never tried, i will make a part 3 video soon with e bike controller, nunchuck and rc receiver, thanks
Hello, i've watched your video several times and i just cant figure out why you used the DAC boards if you're going to get a USB Host Shield which would be connected to the arduino UNO from the top, therefore i wouldn't be able to connect the DAC boards, so why did you use the boards here and how are you going to connect the USB Host shield afterwards?
Thanks
hi, the usb shield clips on top yes, it also has output pins on it like the arduino, it uses some pins (9,10,11,12) for usb functions but all the others are free i think, the DAC run through I2C so that makes it even easier, im my case i have a sensor shield on top of the usb shield, this just makes things a little easier connecting, so just to round up, its arduino board, usb shield on top, then a sensor shield, then the DAC connect to the SDA and SCL pins for the I2C, hope this helps, thanks
Hey, I'm curious what code you downloaded to the board before using arduino. Just with the two potentiometers? Also, what sources did you use for this?
hi, its the same code, just using the arduino allows you to offset the potentiometer values, there are lots of people who have put things online, blogs, projects, some of the github libraries have detailed records of their projects, hope this helps
How did you connect the Green blue and black cables. Like you took the plastic off and then what
ok i took a plug of an old side sensor board and just wired the ends of that
when i saw rhe servo i was so disapointed , im so glad its not that.
i have been looking for such divice for so long, my project its to control a longmower via internet
@@Biblogie ok great, happy to help, feel free to let me know how its going, i need to get my hoverboard car controlled over the internet, something like 4g from a wifi hotspot maby, thanks
does one need to use steering pot? what if we making a trike and dont need that.
hi, i think you would need one to set them to be the same, if none is connected im not sure what would happen, they might go the same by default, you could probably connect a potentiometer to the steering for a bit of electronic differential, i think even with a trike the rear wheels would want to go different speeds, hope this helps
@@A-tech agreed. Just rather not have extra dials a kid can play with. Maybe i mount on steering column with gear to accomplish the differencial when steering.
But from what i see in your video this would also mean if steering is turned with no throttle it would still activate which is why i rather not have it at all
congratulations! my board has the at AT32F403RCT6 component. do you have the procedure to apply on this type of board?
i dont know sorry
فديو رائع جدا نفعتنا فيه كثيرا.بالتوفيق والنجاح أنشاء الله.خمس نجوم.
nice . did you manage to use this with ebike throttle ? and use regen braking ?
hi, still havnt tried it yet or the braking, i will try and do a part 3 video soon
Nice tutorial A-Tech. Is it possible to control both directions by potentiometer or maybe some additional switch? I actually don't need the differential. I would rather avoid the motor phase switching. It would be better to control this at input site. Nice work again!
may i recommend using a different firmware?
@@A-tech yes. sure
Hello again, great vid used it for a few projects. Is there a reverse function?.
hi, yes if you do the speed potentiometer past the stop point it will go in reverse
Where can I find the Mount that you use for your wheels thanks? Love your videos.
ok they are just 16mm shaft support brackets, thanks
Couldn't PWM be used to change the speed of the wheels? changing the voltage from 5V to 3.3V with a MOSFET
hi, these motherboards support lots of different input types, pwm being one of them, I like to use the DAC as a safety thing, I have tried serial coms before but the motors would continue to spin if the controller crashed
Dear Sir thank you for all the explanation for modifying the board but i have a question how can i program the original firmware for the hover board and can i get it from another working board
Not possible
Great Job, can you get full speed while in the reverse direction ? Or only half speed ?
hi, at the moment only about half speed but full speed would be good
Hello, these are great videos you have done on hoverboard hacking. I definitely want to use the arduino like you have to control the motors using a wireless joystick. Will an arduino UNO rev 3 board work well for this? I already ordered the breakout modules and am looking for the controller that fits my need. I'd like to use the 2 axis joystick you showed - but only make it wireless. I'm just a bit fuzzy on how to integrate the arduino as I've never used one before. It doesnt look all that hard, I just want to make sure I get the right stuff. Thanks for posting all these ow to vids - the tank is super awesome!
hi, yes arduino uno is fine, i think i have had these running off a few different arduinos, as long as you set up the DAC in the code it should be fine, i have another video about using a ps3 controller with arduino, you will probably find that helpful, thanks
It is possible to control motors by sending commands to stm32 microcontroler on driver? Id like to send command ex. Drive pwm 162 to mc from arduino by uart or i2c or spi
hi, i tried spi once and it worked well until the arduino crashed and the motors kept going, you just have to put extra safety stuff inside, thanks
Did you have a version of this code that works with the ps2 wireless controller?
hi, i have the code that works, im currently using it with the mobility scooter part 2, that is rc, video should be up shortly and i will put the code in with that one, thanks
Hi! Is it work with normal ebike throttle (with hall sensor) ?
hi, i cant say yes or no, but if it works like a potentometer then it should do, you may need to map it with an arduino
Thanks for the explication, is there possibiliy of flashing the hoverboard dual motherboard
I dont think so, thanks
I thought the new firmware allows direct serial line commands from arduino, no need for DACs ?
hi, apparently it does yes but im not sure how to do it and from what i have read it isnt as reliable, thanks
Just flashed the latest software from the link and it doesnt work at least on just potentiometers connected :/
had some feeling at some point that it kind of works as adjusting potentiometers was chaning the capacitors recharging frequency (it's heardable), but somehow stopped doing that :/
The software definitely loaded on the device as when it starts needs keepeeng power button on to stay up.
I just assume that the latest software was for different input type. Anyone go the software version used on this video ?
hi, its possible they have changed it but i dont remember needing to hold the power button down for it to work
Hello, how would to code work for steering for an autonomous setup like this?
hi, its hard to say in a comment, but it would need data from a gps and or sensors or lidar, and be able to adjust its route depending on what is around it, i will be making one eventually but im not quite at that level yet, thanks
Thanks for this wonderful video. I'm having trouble with the wiring etc. The battery wires attached to the board is cut off. When I try to attach it to the battery it sparks. I tested the battery with another board and that works fine. Can you gimme some tips? Also is it possible to have a chat with you? I need some more direction. Thanks in advance
hi, they usually spark as its charging the capacitors, i use a switch so its a bit better, do you have another battery to try in the suspect board? what are you making? thanks
If I use a Ps4 controller, do I have to modify anything from the code or other parts in the build?
im not sure about ps4 controller
Hello. Great vid my ST link is in the post and can't wait to try it. Will the pot method work for just one motor?.
hi, thats good, yes i dont see why not, thanks
Hi, nice video. I have a few questions:
1. How can I set it for reverse? like for go-cart. In your video the steering pot seems only control either one wheel and turn into a different speed and direction. What I want is actually simple, I want to steer it forward with the same speed, and I can also drive it reverse (with a switch or else). Can you tell me how can I do that?
2. Does the battery charging feature still work?
3. How fast the maximum speed can we set in the code?
Thanks before.
hi, ok there are 2 pots, one does speed difference, the other does speed for both, so for reverse you just turn the speed one down further than when its stopped and it will go backwards and bleep, for example the 1024 pot value would be something like 0-300 = reverse - stop, 300 - 1024 = stop - full speed, do for your DAC if you are using one you need to split it like that if you are controlling forwards and reverse with 2 buttons / sticks.
Apparently the battery charger does still work, however i am yet to test it.
Max speed depends on what firmware you are using and if you change stuff in it, the fastest one i have tested myself is the bobbycar version, it has a speed setting you can set when starting up, i think with a 12s battery it can get upto 30mph, its a feature called field weakening, there is more info on this online if you google it, i just set it in the firmware to run off a 10s battery and its fast enough, maby 20mph.
There is a guy who hosts an online firmware compiler that i have used a few times, you can edit the code online, compile it and download the .hex file to upload to the motherboard, here is his channel: ruclips.net/channel/UCLUfNuoSML-vkLYiO0vBUHQ,
hope this helps!
thanks
@@A-tech thanks for your reply, I'll try it.
Can I work two of these controller at the same time?
yes you can run as many as you like, i had a car with 2 of them driving 4 wheels and it was good
Hi, According to the wiring diagram I found, the hoverboard has 2 sets of gyro inputs, the diagram you showed only uses one blue wire and one green wire. How does that work? Thank you!
I'm fairly sure the custom firmware he installed bypasses the one gyro input, because in Part 1 he just cuts the wires for that input.
hi, sorry for the slow reply, yes in part 1 it shows a bit better, you only need to use 1 sensor cable because that does both, the other is just for the leds and stuff
@A-Tech Is there a way for for the main motherboard to drive a sensorless motor and if so how would be
i dont think so, thanks
@@A-tech thanks for responding and if you do find a way please let me know
Why did you map 10 bit analog in to 8bits just to scale the numbers back up to 12bits for your DAC
hi, sometimes i just keep adding bits to the code and dont go back to refine it once its working, i really didnt notice, thanks
hey, i connected the potentiometer but when i get to half of it the motor is at max
hi, what value is the potentiometer? i use 10k ones
What potentiometers do you use??
hi, 10k ones, thanks
Hi a Brilliant Hack . Many thanks , if it Possible for you to do a mod to this hack . by controlling the motors digitally rather than analogue input for example via serial monitor commands . That would be very interesting addition to this video . Once again Many Thanks .
hi, i tried the serial way and there was a problem if the arduino crashed the robot would keep going so i had to use DAC instead for an extra level of safety
Can we control the motor separately by two different potentiometer?
i dont think we can, thanks
I don't know what i'm doing wrong, i hooked up my potentiometer to the long cable for speed like in the drawing(3.3v to left pin blue to middle pin gnd to right pin), and i have my firmware set to variant_adc, i'm not sure what to put the values at, but in the firmware it says it can be auto calibrated, so i just left it at the defaults and have tried the auto calibration, but the motors don't turn when i try the potentiometer out. I really wish there was a discord channel for discussing hoverboard firmware related stuff.
hi, did you get it sorted out? i dont think we need to change any values just upload the new software and should be good to go, i would like to set up a discord for this kind of thing but not sure how it works, thanks
the hooverboard i took apart didnt have a motherboard only the 2 balacne sensor bords
yes you need to find a video for your hoverboard
Great job, can I use it for a scooter with one or two electric motors?
Yes, of course
What kind of potenchiometer did you use?
just a standard 10k
Hello, I have successfully changed the software in the Mainboard, but i must adapt the values of the throttle in code. Could you tell me which value should i change for lower max voltage on throttle?
Best regards
Jakub
hi, do you mean to set a max speed?
find this line of code:
"dac2_value = map(set2, 120,0,1600,4095); //forwards"
so the 4095 is the number for max speed, 1600 is stop, so any number between them two instead of the 4095 should reduce the max speed, hope this helps
@@A-tech hello, thanks for your reply. I want to increase the max speed.... I have made some test mit motus Scooter. Motus has 350W motor and in our project the motors have 2x540. Motus was faster, greater max speed and so one... So I think the throttle don't give full 3.3v at max load. i have to measure the max voltage of the throttle and adapt the code for my throttle. 4095 is 3.3v?
Hey, I want to use a PWM receiver as the input. I have got the code for it but I am unsure of how I should go about adding it. I'm also not sure how the wiring is required for the DAC's. Thanks
hi, do you mean like an RC receiver? im sure there is a way to do it direct, you can do it with an arduino which might be easier with the mapping of the throttle and steering ranges, the DAC is pretty straight forward, they use i2c to communicate with the arduino and need a 3.3v input so they only output 3.3v max to the hoverboard, does this help? thanks
@@A-tech Yeah I want to an RC receiver, there was a custom firmware to make it work directly but I could for the life of me get it to work. I am very new to Arduino so I'm not sure what pins to put the DAC's according to the code on. A wiring diagram for the DAC's would be awesome. I know I am asking for a lot but just a look over the code to see if my implementation for the pwm is correct. Thanks for the reply.
ok im not sure, havnt done much with rc receivers and hoverboards, arduino pins for the i2c communication are named SCL and SDA or A4 and A5, im going to do a Firmware Hack part 3 video soon so i will make sure to include that
@@A-tech That would be so good. Thank you. I am building a driving esky. Already got the frame and everything built and just trying to get the electronics to work. Thanks once again!
hi sir
In your previous videos, you are using an motor controller called flipsky. Is the Hoverboard motherboard as good as this motor controller.
Also did you try any encoder with these motors. Thank you for answers.
hi, the main reason for the change was they are so much cheaper, the flipsky ones are about £50 each and that does 1 motor, the hoverboard ones are around £20 each and they do both motors and also handle the charging of the batteries, all connectors are already fitted, and the flipsky ones can be tricky to set up, none have been used with encoders only the internal hall sensors, hope this helps
@@A-tech thank you sir. This was very informative for me
For me after the software change as soon as i give it any voltage, 0-3.3,to blue or green it only spins both wheels on 1 constant speed. Tried it with the dacs as well as simple potentiometer..
ok 1 should do speed and the other should do speed difference between the 2 motors
Do you replace the potentiometers with a controller?
yes, arduino and 2x DAC, thanks
@A-Tech. You did an awesome Job. Would you be able to connect the Arduino UNO to a Flyshy FS I6? if it can. Can you please provide the wiring Please?
hi, im not sure i dont have one of them, is it a rc receiver? i did it with a futaba and a dumborc with good results
How do I bypass the 4 feet optical sensors for forward and back
I got 2 separate controllers linked via 4 pin wire ....might try opto couplers
you could try using a servo with a blanking flap?
@@A-tech I forgot to add 1 wheel failed to run but think it only needs 1 sensor then it looks for the level sensor is it a accelerometer
I have to tilt the PCB for forward and reverse also speed control mmm
There's a bit of damp and corrosion on that PCB .... I've checked few components aiming for SMT capacitors capacity of the one was below 2uf and the rest was 5uf would that stop it from moving mm
@@davey2k12 ok yes thats right i think it does only look for one pressure sensor, im not sure if it would stop it moving, but corrosion is usually bad for a pcb, do you need to tilt both sensors at the same time?
@@A-tech oh yeh maybe that's why only 1 wheel runs board might be trying to turn one way mmm, might be 2 accelerometers on each PCB working independently for steering good call bro 👍
@@davey2k12 I think so yes, im pretty sure when i rode one before you could tilt one foot and only that side would move, no problem
And yes I would love to see the ps3 controller video
ok it will be out soon, thanks
@@A-tech Did you ever post a video on the code and connections to use a PS3 controller with the hoverboard motors? Thanks
which board to choose when you compiling sketch
hi, there should only be 1 board, thanks
Nice work. Can I connect a Nintendo nunchuck joystick instead of the two potentiometer direct to the motherboard ? Does this work the same? Could you guide me about this?
Hi, thanks but I don’t have any Nintendo nunchucks
WERI nice
Can you do a video connecting a nunchuck control
hi, im planning on doing a firmware hack part 3 video, this might be included, thanks
No me funciona, no esta claro las conexiones.
whats the hoverboard model and brand that you are using in this video?
hmm that would have been good to include, its a generic hoverboard, best way to tell is by the wheels i think, hope that helps
@@A-tech thank you, I see the generic is usually call Two Wheel Self Balancing Scooter
What happens if you do this without downloading the software?
im not sure how you would do it without the software
Whats the code for the ps4 controller? I cant get it to control the wheels.
hi, have a look at my ps3 controller to arduino video, thanks
what pot values did you use?
10k
Hello, I have a couple of questions. I dont understand the setup at around 7:07 . Like the gears you used and if I would still need them if I would use an Arduino and controller. Also could you please elaborate on controller the configuration and how you connected it to the arduino? Thank you
And what arduino did you use (the one in the picture ( 8:35 ))? Or can I use my normal Arduino? (www.amazon.de/dp/B01EWOE0UU/ref=sr_1_7?keywords=arduino&qid=1583182710&sr=8-7)
hi, that was just a joke, its really not a way you should control a potentiometer, ok the controller is a ps3 controller connected via bluetooth, you will need the ps3bt library, hope this helps
that one is an arduino uno, thanks
A-Tech so I can also use my Arduino which is also an Uno
@@relatedl35 thats it ye
anyone knows how to do it on 3rd revision ?
