Serial Servo HATs and Raspberry Pi, Arduino expansion boards 3:15 pm October 2, 2023 By Julian Horsey While building robotics projects, the importance of controllers and motors cannot be overstated.

The Raspberry Pi already makes a pretty great computer for a webcam, but if you want to actually control what that Pi is looking at, you'll need actual movement.

He just threw a Raspberry Pi in for interfacing to the Internet and an Arduino in to control two RC servo motors. A zip tie holds the servos together and potentially the web cam, too.

By connecting the Raspberry Pi to a network of motor drivers, we can control the motors in realtime without overloading the Raspberry Pi. The original idea of the SlushEngine was to keep it simple.

DIYer James Wahawisan figured out how to control some with an Amazon Echo, Raspberry Pi, and a few other parts.
