Raspberry Pi Zero Devastator robot improvements -- using Pygame to read the keyboard, and the PWM inputs of the L298N for motor speed control. You can download the code for this and previous episodes from: https://www.explainingcomputers.com/pi_devastator_videos.html The first three episodes in this series are: Raspberry Pi Devastator Robot #1: https://www.youtube.com/watch?v=DyQxvfwQbTg Raspberry Pi Devastator Robot #2: https://www.youtube.com/watch?v=j6mglfhWZrQ Raspberry Pi Devastator Robot #3: https://www.youtube.com/watch?v=pK0XvjiP2qk IMPORTANT NOTE: On October 30th 2021, a new version of Raspberry Pi OS was released known as “Bullseye”. This has new camera drivers that are not compatible with the Python camera code demonstrated in this video. Sorry. If you are running the version of Raspberry Pi OS known as "Buster", or an earlier version, things should work just fine. I discuss the matter in depth in my video here: https://www.youtube.com/watch?v=ykM5bvVURJw More videos on SBCs and broader computing and related topics can be found at: null You may also like my ExplainingTheFuture channel at: null Chapters 00:00 Introduction 01:04 Project review 06:25 Reading the keyboard in Pygame 09:24 Pygame robot control code 12:09 First test 13:27 PWM speed control 16:42 Final test
