We’ve: Unboxed and assembled a UCTronics Robot Car.. Set the car up as a Wifi client and installed JupyterHub. Connected a wireless gamepad. Replaced Wiring Pi with pigpio and read from a sensor It’s finally time to make this car move. You’re going to talk to the motors! Using pigpio In the last post, we left off with code that looked like this: import time import pigpio def beep(count): for i in range(count): pi.

So far, you’ve unboxed and assembled a UCTronics Robot Car. Then, you set it up as a Wifi client and installed JupyterHub so you could write Python code to control it via a web browser. Just before the holidays, I dug up my old post about reading a USB game controller and refreshed it, so you can use a gamepad to control the car after I go over how to control the motors.

Last week I wrote up how to prepare the UCTRONICS robot I’ve been playing with for hacking.. This week, I’m taking a break to update an old tutorial from five years ago: how to use a gamepad to control a Raspberry Pi. This post has been around a few years, and I just found out that a bunch of images broke, so it’s time to update with a new Pi and easier-to-follow instructions.
