Thanks Raspberry PI Guy! Your tutorial is very clear and concise and to the point. I think many people will find the tutorial inspiring and useful. And therefore a well meant thanks is more than deserved here. I will try and use this information to develop an autonomous gps controlled boat. THANKS
This video is great and really helped me out, so thank you very much :) The only thing that I noticed is that in the video, you suggest that the +5v power on the L298N board is needed to supply the bridge with power (in which you did using the +5v power GPIO pin on the RPi). This video is the only resource on the net that claims that +5v is needed to supply the board, as all other information states that the +5v pin on the l298n bridge is to output a voltage to other peripherals. I tried out the l298n without supplying the +5v as stated in the video and the chip performed as expected and did not need it. Just to let you all know :) Good work!!
Excellent tutorial! Sound and picture is very good. Pacing is good and subject matter is very interesting. I wish all Raspberry Pi/DIY electronics videos were like this. A genuine joy to watch :)
Thanks again. Just spent time with my daughter converting a small robot using this. We used two wheels (easy enough) and, other than being a little under-powered, it worked great. I didn't want to have anything connected such as a keyboard so I set up SSH so that I could remote into the Pi and run the programs using Putty from my Android tablet. Look ma! No hands!
Thank you so much. This is an excellent step by step guide. I have an older robot built with some old power screwdriver motors but we had to control it with switches and walk behind it. That robot was built with my Son and now I'm going to use this to update it as a project with my Daughter. This was exactly what I needed.
It's probably not necessary (or advisable) to connect the +5V terminal to the Pi. This is actually a 5V source from the on-board 7805 regulator. Not sure how much surplus power is available, but it should suffice to power a small AVR.
Good explanation. I have one question for which I believe other people may have too: How to control speed of the motor(s)? This is because sometimes we don't need our robot to run as faster as possible, but instead very slowly - especially when some detector (ultrasound) is attached to help avoid obstacles. If speed is too fast, then robot will bump into obstacles too often. Than you in advance, milan ---
KKuurus I am not still sure delay what? To make short pulses, then delay? Or, something else? Or to use PWM? Does this device has PWM at all? Sorry for too many questions, but before to make decision whether to invest money into this 'toy', I want to know what exactly I need for robot (I have plan to make one, maybe in distant future... low on budget right now).
by looping through a delay before you reposition the servo/stepper you can slow the movement of the motor. in the software driving the motor, will slow the movement of the shaft, PULSE delay delay delay Pulse Pulse delay delay delay
the only way to control a dc motor with 2 wires is to adjust the voltage going through the motor. you can easily do this by making simple 5 transistor circuit on the power supply for the motor and using a potentiometer to controller the current going through the transistors.
Very useful tutorial. I've been doing some ATM with an Arduino board and components, and I find controlling and programming things from Raspberry PI very similar. I think I will try it when my RPI would have arrived.
Hey, I've been subscribed for a while but only recently, after moving house, got an internet connection and thus been able to use my raspberry pi wirelessly. I'm finding it difficult to follow a lot of the instructions. I guess I have a weird learning style in that I find it easier to just get what I need to do to make it work then learn the technical stuff about why it works after, I can never remember the names of things otherwise!
You don't have to connect the first Enable-A cable from your video. As long as the second is high, the chip is enabled. This is also the input to use with PWM to control the motor's speed.
I found what I think is a slight issue with your example, enable A/B you don't have to use the 2nd Pin. I followed your setup, both enable A pin 1 and 2, and not using the pin 2, and the results are the same, only the front most pin for enable A/B from board edge has to be set to high. The board documentation suggests that enable A/B are actually already setup for PWM, so setting enable A/B to high, is driving the motor at maximum speed. Have you tried using soft PWM to drive enable A/B?
If you had 4 wheel attached to 2 L298N's could you set it up to take user input,for example 'left' will stop the left side motors and start the right side ones for say 2 seconds for 90 degrees (ish). If you had a wireless keyboard you could remotely control your raspberry pi to move if you had a user input programmed in. (I'm new to python and I'm not sure if this is possible)
Hello Sir, I managed to make the connections and also run the code properly. Thank you very much for the video. But I seem to be facing a problem, the motor gives a few spins (2 or 3 mostly) and then stops, it just doesnt respond. If I reconnect the ground connected to the motor driver or run the script again, it spins again a few times and stops. I have tried multiple tutorials but cant seem to identify the problem. I exactly replicated the wiring shown in your schematics. The motor is powered by 4 AA 1.5V batteries just like in the video. Only time this problem doesnt seem to occur is when I apply 20V 1A DC supply from the adapter and I cant possibly use that 20V coz I want the roboCar to roam freely (not plugged in to the wall).... Can you please help me identify what I might be doing wrong?
Is it possible to bridge the ENA pins with a jumper, like on one of the photos? In my opinion the Motor should be enabled the whole time. And now I can simply turn on and off the motor by setting the input pins for the directions on and off? So I would have 2 pins more for other stuff...
4 battery pack with 4*1.5v = 6v (if you are using non-rechargable batteries). Raspberry takes 4.75-5.25 input voltage. Is it okay to give 6 volts from battery pack to h-bridge+raspberry? If it so, can I use 4 rechargeable batteries, which will provide only 4 * 1.2v = 4.8v? Will it be enough, or should i use 6 battery pack(with 5 batteries), in order to provide 5 * 1.2 = 6v? I'm so confused about it, can someone explain me please?
I'm doing a project in school where I want to be able to use the Pi to unlock a locker in some way. Is it possible to do this using a L298N? I'm completely new to programming.
Is it possible to control any type of motor with a raspberry pi or arduino? I would like to use the actual claw machine from a real arcade machine, would I be able to control the motors on the claw gantry(x-y)? They look like dc motors.
Would it be easier and/or more efficient to control motors that are connected to arduino but controlled by raspberry pi. I've already successfully done this but I was wondering if excluding arduino and only using RPi would be more beneficial. I'm working on converting a RC car into a car that will connect via wifi to be controlled by inputs on my computer and receive a live camera feed and later I plan on making the car autonomous by adding sensors.
Super great explaination, but i don't know why, mine is not stop with CTRl C, it just continue spinning, so where i can find another tutorial to set speed of the motor?
Nice tutorial! That exactly what I need. But I tried and found the rpi can't work however. When it started screen can print some messages, Particularly the network module can't work, neither wired or wireness. And the power I use is 12V. So I doubt the gpio 5V if whether can as the power input? I also see the circult diagram, it didn't has a diode, then I can't how to do next, appreciate for any advices.
Thanks, Could you please tell us how to do the same thing but with controling the motor via the internet. Let's say i am in a city and my pi is in another city.
Are all L298N Modules the same? The one recommended here is sold out on ebay so is this one ok, the Dual H-Bridge Motor Driver L298N Module For Arduino PIC DC Stepper L298 Board, even though it is for an Arduino? Thanks
Thanks for the video pi guy. Watching this video inspired me to start a robot of my own. I'd always wanted to do so with one of my pi's, but I always assumed it'd be too expensive and/or difficult. My first iteration is here: Raspberry Pi KNEX robot
Use the A side (ENA, IN1, IN2) connected to one motor and the B side (ENB, IN3, IN4) connected to the other. Note the "back enable pins" are not Enable at all, but +5v. You may jumper between the front and back to permanently enable that motor, or connect the front Enable pin for each motor to the Pi. Do not use 4 wires for Enable, only two, connected to the front pins, the ones even with the IN row.
Thanks for the Video! It was very informative and gave me a starting bases for my robot project at school, but for my project I need to control 6 motors. As far as i'm aware I need to use 24 gpio pins to control them all, however the pi only has 17. Do you have any solutions? Thanks in advance.
OK :) It is a good video If you are Matt Timmons- Brown Learn Robotics with Raspberry Pi ....Problem...Chapter 3 page 62 to page 66.. You lost me and maybe a few others on this exact wheel motor on wiring in your book both wires are red. Not sure why one isn't a black or blue to show the difference between the positive and negative hook up. I am sure this matters in some way Let's go with page 62 Neither the motor or the wires tells me which is positive or negative I'd rather know then guess any tips?
Hi Scott! Thanks for your question - you can reach me at my email address or on Twitter more easily in future though. Just taken a look at that page and you don't need to worry. DC motors like these do not have a particular polarity, and so you can run electricity through them either way. In actual fact that's how you get them to go forwards or reverse - electric current one way or the other. That is why both of the wires are red in my book - the orientation doesn't matter.
@@scottrocket3274 it is the same deal with the motor connections on the breadboard - the polarity and orientation of the wires is not important. Hope that helps :)
I have a robot that has 2 6V motors (pololu.com/catalog/product/1060) and would like to achieve what you did in this video. I will be using a raspberry Pi. Can you recommend a servo board that I can use? Or will the one in the video be enough to power both the motors that I have?
Why would you put pins into screw terminals? It looks like that board has pins right next to the screw terminals you can use to power it. Also why are you wasting two GPIO pins on "enable A" when you can just hard wire them (this is even shown in one of your stock photos -- you can clearly see someone simply just put a jumper over the enable pins!)
But by using two GPIO pins for the enable you chew through a lot of pins. I'm controlling four motors identical to yours so I need to economise. I'm only using two pins per motor. I hold one low and PWM the other for forward and round the other way for reverse. On the driver the enable pins are jumper end together. Easy.
+vikas narang as I said, I'm using two pins. One acts as the ground and the other has the PWM signal. Swap for the other direction. The swapping gets done in code. So I've used 8 pins total for 4 motors but I can control them all independently.
so i want to control a RC car motor speed, so i need more, power can i simply replace the battery source with the rc cars battery pack, it uses a "Lipo Battery 1500mAh 7.4V 2S 25C"
Please explain what the point of this is: pin 7 -> A enable 1 pin 11 -> A enable 2 Code: gpio.setup(7, gpio.OUT) gpio.setup(11, gpio.OUT) gpio.output(7, True) gpio.output(11, True)
Thanks, that is what I thought but wanted to make sure the relay would not act as a simple on/off switch. I guess I should have said, Can you control the speed despite the relay.
would i be able to use a 1500 mah NiMH battery from a traxxas rc car to power my motors? or would i fry the arduino. Also do you have a video showing how to hook a xbox360 remote to rpi?
Depends on the voltage of both the battery and the motors. And to hook up a xbox360 remote to the pi plug in the cabled version or buy the wirelss controller for windows/PC

Does it matter which GPIO pins we use to give input? (I mean , can we use different combinations?)
Thanks!
nice tutorial for beginners.....
I always wanted to make a Pi robot, thanks for uploading this!
If you are using 2 motors do you need a higher voltage from the battery or will it just run out faster?
Could you use this if you wanted to control 5 or 6 motors? Also if you have more than 1 motor control board do you have to ground the Pi into each?
Is it possible to control any type of motor with a raspberry pi or arduino? I would like to use the actual claw machine from a real arcade machine, would I be able to control the motors on the claw gantry(x-y)? They look like dc motors.

i see amazing, but, how doing combining between library opencv with bcm2835 to control motor?
Can you control motor speed with the L298N or is it just an on and off function??
You control motor speed with your program in Python
Thanks, that is what I thought but wanted to make sure the relay would not act as a simple on/off switch. I guess I should have said, Can you control the speed despite the relay.
Chris Kaspar The L298N is not a relay... it's an H bridge. A relay IS a simple on-off switch.
Now that it came out the 5$ Raspberry are you going make new projects?
would i be able to use a 1500 mah NiMH battery from a traxxas rc car to power my motors? or would i fry the arduino. Also do you have a video showing how to hook a xbox360 remote to rpi?
Depends on the voltage of both the battery and the motors.
And to hook up a xbox360 remote to the pi plug in the cabled version or buy the wirelss controller for windows/PC
thanks
Is it necessary to put 12V to L298N? Why not us the power on Raspberry Pi?!
do you not need to use diodes across the motor then?
Is there a way to do this with an ESC and an AC motor ?
my motor is working fine most of the time, but sometimes it is making a buzzing sound and it is not rotating. Does anybody now why?
The pins retain their states when the program exits. You should kill the program when the motor is sleeping idle for the 2 seconds.
Nice!👌
How put push button ?
