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.

I used a servo controller and two motor controllers from Pololu. They are still available and I’m using them on a rebuild, this time using the Raspberry Pi as the brain.

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.

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.

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