@@lampfall7915 Hi, sorry for the late reply. Not exactly, they are two different codes, as the first code shown for the transmitter and the receiver are for an airplane, which has completely different controls.

I'm really glad that you found it useful! Thanks 😊✌
This is just what I needed.. thank you for the free code...
I hope u get loads of subs...
I'm very pleased you're pleased... thank you!
@@MaxImagination hey max, can we use this code for drone
Amazing, I have all the parts at arm's reach! that has to be a first for me.
The only bit I'm a bit dubious on is running the NRF modules from the Nano's regulator, I've found these to be quite fragile and easy to kill.
Great! About the NRF modules, if you have doubts using the Nano's regulator, try using a separate "AMS1117 3.3V" regulator each to power the transceivers with.
Hey! Max you are a good guy
This video is very knowledgeable
Thank you
Thanks a lot for your kind compliments!

Have you identified the core issue with your NRF transmitter?
Don't give up... You can do it!
@@MaxImagination I can't find the issue till now 😞
I suggest you search for NRF24L01 tutorials on youtube to clarifiy the issue you have. Perhaps you can look on troubleshooting forums and try a list of different methods to solve your problem. Keep trying.
THANK YOU
Fantastic max, my son is 10
years old, he is crazy on these stuffs.
Are u taking any online sessions.
If no u should start to share ur skill set, and this will bring exponential max to this universe.
Great job, be healthy to do more like good work
Hi there! Thanks for your comment. I usually don't provide 1 on 1 sessions as I mostly spend my time on managing the current work that I do here. Will keep it up. Cheers!
@@MaxImagination thank you for kind consideration, max
For ten years old, this transmitter is suitable.
Great video. You should learn about BMS for your li-ion batteries to be safer and get more time out of them.
Thanks. I am aware of the importance to using a BMS in 2+ S series battery configurations. This controller's battery didn't get one as the charger is a 3-wire one with a built in bms board to balance charge.
Thank you
ive built the transmitter and reciever but ive downloaded the code and its not working idk if the code is correct or not but is there anything i can do to check it
Hi there. Be sure to carefully check and troubleshoot your wiring that it goes along whats on the diagrams and that your boards are getting sufficient power. Check that you've typed in the correct Arduino board pins in the code for both the Transmitter and Receiver. Just a couple of important things to take note of when checking for what can be wrong.
Cheers,
Max
Wow what a man bro
Please make a drone fully controlled using arduino 👍😃😃😃
Thanks for commenting!

This is so cool. Do you know if the transmitter will work between boards? Arduino namo and a pi pico for example?
Hi. Good question. I have never tried using the RPI Pico in a project before. You may need to research that board with NRF24L01 communication a bit more.
Hey! I have a little question about the 8 channel receiver and transmitter tutorial, in it, the guy shows a schematic and on it he shows that the 5v line of the joysticks are connected to each other with no connection to the arduino 5v or the nrf 5v module but the ground is connected to th nrf’s ground. How will the joysticks work with no actual 5v power?
Hi! I just checked the same diagram you were pointing out about, I saw that it was actually the guy's mistake not connecting the joy sticks. So yes, do connect the joy stick's 5V lines to the arduino's 5V.
Cheers ✌
To answer your question, no, the joysticks won't work without being connected to 5v
Thanks so much!
just 1 question, what is the name of that metal glue or whatever you are using behind the pcbs?? please help
I assume you're referring to soldering tin (or lead) that's used to connect components.
Please advise for the maximum distance could the receiver respond to the Transmitter. Thanks
They say it can transmit up to 1km with perfect conditions & decent power supply.
Cheers!
Hi Max, I'm your new subscriber. i love the build, may I ask the range of the transmitter to the receiver? I want to build one for myself.
Hi Glenn, thanks for watching! Depending on how well you've got the power to the transceiver modules filtered, range can go up to 1KM.
Hey max, May I know the the size of the wires you use to solder the batteries together and any other wires you used other than the 30 Gauge wires you have listed in the video. Thank you so much.
Hi there. I used 20-gauge (20AWG) Wires for wiring the battery. I typically use 24AWG wires for my circuits which are a bit thinner. Cheers.
@@MaxImagination Did you use the 24-gauge wires to wire all of the circuits in the video along with the few times you used the 20-gauge wires and the 22-Gauge copper wire?
Can I use 22-gauge wires instead of the 20-gauge for the circuit and battery or will cause some issues?
Also is it possible to use a stripped down solid core 22-gauge wire instead of the copper wire?
One more thing if you don't mind..
Can I on tx attach the push button pin (sw) from one of my joysticks to ch5 or ch6 as a digital read?.
Then on rx solder a rc on/off switch I bought from ebay and have the push button on tx activate it?
I have hooked it up but nothing happens.
Push button on stick is digital right?.
Hi there. Yes, you may do so.
About the RX's ON/OFF switch, I don't quite understand what you meant by that... Do you mean you want to activate the RX remotely?
Also yes, the Joystick's built-in push button should be hooked up digitally. Cheers.
Is the 3.3V voltage regulator mandatory since the arduino nano has both the 3.3V pin and the 5V pin so it can be conected to the nrf module and all the servos or motors.
Not mandatory, but recommended for a more reliable supply. I suggest placing a 10 microfarad capacitor for power ripple filtering at the power terminals of the radio module if you're powering it from the Arduino's 3.3V supply.
He podido medir el alcance de los nrf24l01 con lna y casi llega los 2.6km. Y digo casi por qué se me atravesó un puente vial en mi ciudad. Solo que traen una pequeña falla con el puerto spi. Se requiere una resistencia entre MISO y los 3.3v
Very good. What value resistor do you need for that?
@@MaxImagination Aproximadamente entre 2.2K y 2.7K . ¿Has podido detectar esa falla en la comunicación que menciono?
Hi there! I've made this for 2 DC motors but I need them to work separately (I am making an RC car). The code that I downloaded from you makes them work at the same time, what can I do?
Hi there. Be sure to run them with separate ESC's/motor drivers and use different channels for each.
Great project 👍.I want to make rc plane.can i use 2 serial connected 18650 lithium iron batterys to get 7.4v for receiver instead of lithium polymer battery for rc plane?
Hi and thanks! Yes, you may do that, but make sure you're building your plane with highly efficient motors - brushless motors to have enough power for the plane to lift off with the heavier Lithium Ion batteries.
@@MaxImagination thanks 👍
Hello bro, loved your work and got inspired to try it myself, but I ran into a problem like my receiver is working fine if I am powering my Arduino nano from my laptop, but when I am powering the receiver circuit with 7.4V battery it is not working instead I am getting power drop. Please can you help me out 😊
Hey and thanks! Be sure to power your Arduino via the "VIN" pin with 7.4V and not the tranceiver module that receiver/transmits data, otherwise you'd have fried it.
Hi Max, will the stearing mechanism work if I use a motor instead of a servo?
Hi Akram, good day! If you're referring to the steering mechanism from my previous video, yes. A standard small DC motor will work as that's what it was built for.
Though, if you are referring to using the transmitter and receiver/controller similar to the one I made in this video, I'd highly recommend using a servo motor for the steering.
Have a good week!
- Max.
thanks very much for the code
You're welcome! 🙂
👍
Is this work if i use different ce and csn pins on transmitter and reciver?
Yes. I recommend pins 7 and 8 as alternatives.
Hi max, I love the build.May I ask something,How to control 4-DC motors and 2-servo motor? Without ESC. Can you please say once🥺🥺
Hi there. Thanks! The servo motors do not require an ESC to run but the motors need some form of motor driver whether be an H-bridge or just a simple MOSFET.
@@MaxImagination Thank you max!
@@MaxImagination I have a Doubt in Transmitter we connects D11 to MOSI But In Receiver we connects D11 servo motor. Is That actually works??
is it possible to use arduino uno with the same program?
Yes, as the Arduino UNO's specifications are almost the exact same as the nano, except only larger.
Hello!
Thank you for the video, it was very informative, however i have a problem when uploading the file to my arduino, it is showing me the message "avrdude: ser_open(): can't set com-state for "\\.\COM3" " can you please help me out on this problem, would very much appreciate it if you could. Thank you in advance
Hi there. Thanks for your comment. Have you tried a different cables? Another Arduino? Sounds like your IDE isn't recognizing the Arduino due to a communication error.
Are you sure you are using the correct com port?
Sometimes arduino IDE can have trouble finding cheap/damaged arduinos
will you please make a breif video on how to connect it with elegoo car
Might do that one day, there still isn't a high enough demand. We'll see
how to add dual rate or end point trimmer because i'm planning to use it on rc car which steering end point is required.
I'm not exactly sure how that would be implemented in an Arduino radio set. Though, I do know that it isn't so hard to adjust the rate values in one of the Arduino's codes.
One more doubt brother, which channel ESC should be connected in ur circuit and code?
If you're using a PWM ESC, keep in mind that it can be connected to any channel above the 1st one (first one or two channels are PPM, not PWM channel).
can i use attiny88 or 85 development board for this project thank you
As long as it's got enough memory to run the code (I wouldn't know its specs) then it should do fine.
P.S. Please excuse my late reply.
Wow Great work. but how can i solve signal interference problem ??
Hi, are you having a signal interference when using this around WiFi? What kind of signal interference are you troubled with? Thanks for your comment.
@@MaxImagination Thank You Sir. The signal is not stable
@@danielkibret8271 Did you make sure to add x2 10-microfarad capacitors at the receiver and transmitter ends as shown on the diagram? Also, try keeping the transceiver modules wired as close to the arduino boards as possible.
Play around with the antennas, sometimes they aren't properly connected internally.
hello, thanks for this video i made the transmitter and receiver and their is a connection between them but i have a problem no channel on the receiver is resetting to 0 for example if i connect a led to a potentiometer CH the led doesn't turn off if the potentiometer is all the way down but i can increase the brightness of the led when i move the potentiometer up even servos don't move or the motor on esc ,i can control the throttle but not turn it completely off. the same happen with switches can't turn of a led but can increase brightness of led when turned on. please if you have any idea tell me
thanks in advanced :)
Hello there. I have never heard of this kind of issue before. Are you sure you haven't changed anything in the code for the receiver channels to be stuck? Apart from this, I have no idea what to suggest...

hey Max im building a Ardiuno rc plane for a STEM project at school and ive built the receiver and transmitter and put all the code onto the ardiunos and there not working, the motors will buzz non stop and every once and a while the servos will have a spazz but the transmitter isnt doing anything with the motors and servos, idk if you can help or not, thank you.
Hi, Eclipse. Please check that you've assigned the corresponding pin numbers that you've wired in your circuit. Also, it may be worth checking that your circuit is receiving enough power.
@@MaxImagination thanks for the help mate
@@mundycustoms You're welcome 🙂
can we use a simple rocker switch instead of that one for the transmitter??

Can you please tell me that how much range can we get with 7 channel tranmitter? And I also want to know that if the range of 7 channel will be less than range of 4 channel or no effect of channels on range?
The range of this TX and RX pair is about 1km. The number of channels does not affect range.

Hi, I want to recreate this for my school project, can I have a complete list of the materials including the wirings?
Hi there. As mentioned in my video, please check the video description below for the full list of parts with purchase links. Wiring diagrams are also linked below.
Hey dude, Can I use this for rc flying drone, What is the range of this transmitter
Hi, sure you may, but you'd need to go looking in a site such as GitHub.com for the code that will make this transmitter and receiver control a drone.
The range really varies on if what additional components you add to the radio module to smoothen its power input, the range is about 100m on mine, and these modules can transmit up to 1km.
Will any other remote of a toy car work on this receiver???????
can teach me how to connect the trasmitter with the reciever
They connect automatically when you power both sides on.
Hey, how do I connect a male bms connector to a charger? I have made the battery but dunno how to make the charger.
Hi again, a battery connector going to a bms must consist of 3 wires, as seen in the video.
One is Ground, the middle wire is the connecting point of the two batteries, and the other is VCC or the positive battery terminal, hope that helps.
@@MaxImagination thanks but again that didn’t answer my question. If I have a charger with positive and negative do I connect the ground with negative as well?
Hi, not exactly, looks like the charger you're using only has 2 wires, am I right? If so, you have to use a BMS-type 7.4V battery charger with 3 wires, not 2

Hello Max , Can i use a Arduino UNO board for transmitter or as a receiver instead of Nano ,, Cause I have one nano and one uno
Yes, anything that can communicate over SPI will work. Might want to double check pinout but even that I believe is the same on both. Also, those "PS2" china gimbals are junk, nearly so bad as to be switches in some cases, Buy the cheapest "real" gimbals from banggood or aliexpress and your xmitter will be 100x better.

Hello i made my tx and rx but when I connect a servo the servo turns and stops but I can't control with tx I check wiring
What type of servo are you using? Have you checked the outputs with your multimeter on the receiving end? I think your TX and RX aren't connected, actually. Make sure you're using a 10uf capacitor across the power terminals of each NRF module to resolve connection issues - or use a more stable 3.3V supply for them.

@@JeffRenko Hey! Good to hear.
1. Make sure your antenna is screwed on tightly.
2. A 10-100 microfarad capacitor at the NRF's power inputs should work to filter out bad noise
3. Make sure your Joysticks connections are soldered - resistive connections need to be firm.
Hope this helps! Cheers.

I tried to make this transmitter and receiver and my wirings are correct, code is uploaded properly and it is getting enough power but the servo attached to receiver is not working. Can you help me ?
Sometimes servos tend to stop working due to a break inside where the wires connect to the board, could you check that? If not that, then I suggest you hook up a multimeter and measure if you're even getting a signal from the Arduino's pins. It may also be your transmitter's NRF24l01 that's not transmitting. It may help to add a 10 microfarad capacitor to its 3.3V power terminals.
@@MaxImagination I've done everything but still it is not working and I thought that my nrf module was faulty but it isn't
@@shayaanansari3419 Could you try with a different device other than the servo such as an LED to check?
@@MaxImagination k I will try
Please reply my question what is the range of transmittet and receiver
Hi again, please read my reply to your last comment
can we connect brushless motor to reciever?
You can, but you'll need to connect it through a brushless ESC.
Cheers,
Max
@@MaxImagination i do have a 30a esc ,thanks bro
Just a newbie question but, can I control 8 servos with just the two joysticks?
Hi there, hmm, I believe it can only control up to 4 servos, but with some additional coding, you may be able to figure out how to make every half-movement of a joystick to make each servo move for 8.
Thanks!
@@Mbb2220 You're welcome ☺
Hey man, can you please answer my other comment?
hi can i use wireless transceiver module for nrf24L01
Yes. It is a wireless transceiver module already.
Hey max I didn't understand the connection between l289 with receiver
Hey! Maybe this can help: ozeki.hu/p_2999-how-to-setup-a-dc-motor-on-arduino-nano.html
@@MaxImagination thanks it helped me a lot
Hey Max !! Can I use it for making an rc plane ?? Using BLDC motor
As mentioned in the video, yes. Even with a brushless DC motor
@@MaxImagination Thank you I made it now tomorrow I will go to test it in park
I am again afraid to try this if the code has some issues like your esp32 cam video
The code does not have issues, it may be due to the recent updates and your lack of understanding. I would kindly advise you to stay up to date with the ESP32-CAM code in the code author's page. Cheers.
if we need any binding between transmitter and receiver
No binding necessary :)
@@MaxImagination thanks
What is the range of transmitter and receiver it is good for rc plane or not
The range really depends on good antenna power supply (Voltage and current), as well as what filtering capacitors you put at the power input terminals of the antenna module.
So to answer your question, the range is pretty good, 120-1000 Meters.
@@MaxImagination which filter capacitor is good for this any idea
@@e-ways140 (As seen and mentioned in the video) I used a 10mF electrolytic capacitor
@@MaxImagination I can use 100MF its correct or not and thank you for responding
Ermn, that may be a value too high for the NRF24L01, if you happen to have anything between 10-33mF, that would then do the trick.
You're welcome :)
Hey ! Can you control a drone with it
Hey! Yes, it's possible.
Hey boy, you did a great work. I made everything according to the film, but I want to connect to 1 ordinary motor, the normal dc motor has 2 wires and the receiver's pin has 3 pins how can I connect the normal dc motor to it.? I also applied coding correctly, but it doesn't work. Please help me connect a normal dc motor to it.
Hi and thank you.
The reason as to why your motor won't work with the setup you have is because the motor needs a brushed ESC (Electronic Speed Controller) with connects with the Signal, VCC, and GND pins on the receiver, leaving you with two wires at the output. You may order these ESCs online
@@MaxImagination Thanks. I didn't understand what you meant. Isn't there a way to use esc without use? Because they're really expensive. thanks
Hi, check out this diagram which shows how you can use a MOSFET to drive a simple motor instead of a proper ESC.

@@MaxImagination Thank you 😍 inside the chart.... Where should I connect the regulator? Because he didn't explain it. Thank you
@@leading6694 Following the circuit on the bottom right, connect the first pin of the Transistor to any Digital pin (signal pin) the third pin of the transistor to Ground (-) and the motor driving pin to your voltage source.
Where should we connect the iro on the nrf to the arduino uno
The IRQ pin goes nowhere.
Thank you very much
And the way you have made this and explained is excellent
Thank you for your positive feedback!
