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 Zero Dynamixel Hat is an easy-to-use board that allows you to connect and communicate with Dynamixel Servo Motors by using the Savage Electronics AX interface circuit.

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.

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.
