Programming a Raspberry Pi To Read a Gamepad

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.
