DC motor PID speed control

GitHub Code (under /SpeedControl): https://github.com/curiores/ArduinoTutorials If your platform does not have access to "atomic.h" (and so you get an error message), you can use the alternative version of the code that has been uploaded to the repository. It is labeled "_NoAtomic". Learn how to control the speed of a DC motor with an encoder using a PID controller. In this video, I walk you through several important steps in this process: 0. Hardware 1. Velocity measurements 2. Measurement filtering 3. PI control 4. Variations For more information about how an encoder works, see our video "How to control a DC motor with an encoder." /watch/0YAYnLTIGTdIY To learn about low-pass filtering, see our video "How to design and implement a digital low-pass filter on an Arduino." /watch/wpgcnI4C-JHCc Parts used in this video: 1.
