In this video I construct a Pololu Zumo robot chassis, interface it to a Raspberry Pi using an L298N H-bridge motor controller, and use Python code to bring the robot to life!
You can see me continue this project with wireless keyboard control in this video: • Raspberry Pi Robotics ...
This video builds on my tutorial: "Raspberry Pi Robotics #1: GPIO Control" -- • Raspberry Pi Robotics ...
Note that this tutorial will work with any Pi (1, 2,3 or Zero).
You can find the wiring diagrams, as well as links for the components used in my Raspberry Pi robotics videos here: explainingcomputers.com/rasp_p...
PLEASE NOTE THAT right at the bottom of the above page you will find important information about whether or not you need to connect GPIO pin 2 (5V) on your Pi to the 5V terminal on the L298N. With my L298N board I did not need to do this. But this will not always be the case.

Chris, many thanks for taking the time to put this and the many other videos you have together. The RPi and good people such as yourself have helped rekindle a passion for technology I haven't really had since I purchased my Commodore 64 so many years ago.

Invaluable videos. Learning what you learn in one of these videos would take you days and weeks of reading!

Thanks for this, just started studying Computer Science Artificial Intelligence in Robotics and this video got me interested in order a Pi and some components to start toying around with in my spare time!

@Jozie88 8 лет назад

I love the way you speak and teach. You're not too slow, and not too fast. Your voice is very easy and effortless to follow and you always explain everything in good detail without being boring. :) Ty so much!

@Jozie88 8 лет назад

One (or two) questions! How much did it matter which GPIO pins I use for L298N motor controller? If I want to connect more stuff on my PI at the same time, like LED matrix (4 pins plus ground if I remember correctly) and ultrasonic distance sensor HC-SR04, do I run out of GPIO pins which I can use? I'm still a bit lost with those ^__^ thanks in advance.

@ExplainingComputers 8 лет назад

You can use any of the general GPIO inputs to connect to the motor controller -- look at about 5:36 in my GPIO Inputs video here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NAl-ULEattw.html to see which pins they are (there is a diagram, lower screen). You will run out of available pins eventually, but not I think with the devices you list and running the L298N. :)

@deangtspecial6689 6 лет назад

I just discovered your channel via a comment in another channel. I am impressed a thousand fold with the presentation. I must say I wish I had you as an influence when growing up. I learned a lot from a single video (the previous one of this series) and it was my first one I have ever watched of yours. I have experimented with an Arduino, and own a kit. I was looking into the Pi as a friend said you can link them to hardware too using an IDE and special libraries, and was looking into chaining both. Had no idea how it worked as I do not own one yet. Now I need a Pi, badly! I will recommend you to anyone who wants to know more about it as you present well.

@boowonder888 8 лет назад

beautiful little motors! I recently found similar high quality 12v motors in an old vhs machine. No gearbox though. If I learn another language, it will be python. I knew some BASIC, HTML mAYBE it will help. Because the script got to be quite complicated in the end. Or maybe it just seemed that way because of all those loops.

@agcreatortn 6 лет назад

Great video and tutorial. Very easy to follow. For anyone watching this video and building along with it please be aware of your hardware. In this video the presenter is using an older RPi with only 26 GPIO pins. The RPi 2 model b and the newer RPi 3 b and b+ broads have 40 GPIO pins. I had to change pin 7 to pin 12 for code to work properly for me. pin 7 was in an on state after boot on my board. You can see the state of each pin after boot from terminal ~$ gpio readall. I learned this the hard way. On my board some gpio pins are in an "on" "up" state. As stated above when looking at my table after running ~$ gpio readall bcm: 4, wPi: 7, name: gpio. 7, mode: in, v: 1, was causing issues for my code. I change to pin 12, gpio. 1 (v: 0, this was key for me) and code executed fine. There are ways to test your gpio's for failure as well. one being gpiotest. you will need the pigpio liabary installed. www.raspberrypi,org/forums/viewtopic.php?t=180505

@ExplainingComputers 6 лет назад

Thanks for this. There is no need to change the code or to us other pins with a new Pi (and indeed in follow-up videos I use a 40 GPIO pin Pi Zero with the same code). I strongly suspect that some of the pins on your Pi are damaged, and hence in a constant "up" state.

@agcreatortn 6 лет назад

I suspected this as well that i had damaged pins. I ran GPIOtest and they all passed. But I think your right, I think at least pin 7 for me is intermittently malfunctioning. I have a new RPi 3 b I just got over the weekend That I thought about testing. Anyways I think your videos are great for learning and fun builds. I am on zumo video 4 setting up ssh. I have a tank chassis that I am going to build following your other videos. I found a 5 in touch screen for the pi that runs off usb and hdmi and doesn't interfere with the gpio pins. I want to use this so I can lunch the code directly on the robot and expand its portability. I have question when using "curses", is there a way to only have the motors turn when holding down the directional keys and they stop when released?

@robinder_ 8 лет назад

+ExplainingComputers Hey there, do these tutorials you are making also work on pi zero?

@ExplainingComputers 8 лет назад

+Videogame hacks Yes, everything here that does not require a Pi 2 will work on the Zero, although you would need to solder on some GPIO pins to do the robotics stuff, and also use a combined keyboard/mouse device -- or a USB hub -- as the Pi Zero has only one USB port.

@robinder_ 8 лет назад

+ExplainingComputers ok, thanks!

@tarunpai2121 9 лет назад

Hey, firstly, I love your tutorials, they're very meticulously made and very well explained. I have a question. Is it possible to build the robot with any motor and bridge? or am I restricted to using the ones in your tutorial?

@kc-bg5ku 4 года назад

@ppqp83 7 лет назад

Excellent explanation, so straightforward! I was wondering if you could explain how to control 4 motors independently of each other (like for a drone or the Rimac sports car) instead of having just two motors. Also, would the Raspberry Pi have enough computing power to receive inputs (other than positive & negative acceleration, and direction) and do calculations upon them? I would very much like to increase the capabilities of a kit I have for a 4 motor robot, but both motors of each side are connected to the same output of a L298 thus acting as one motor on each side. Thank you in advance!

@sanupamu 7 лет назад

@lieutenantmiller2039 5 лет назад
