Overview

An automaton type of robot that can create anything from simple up and down movements of a character all the way through to incredibly intricate, complicated scenes with multiple animated characters, and even such incredible feats as figures that can draw illustrations or write words with an ink pen!

One of the primary mechanisms found in nearly all automata is the cam follower. In this project we'll build such a mechanism and motorize the drive wheel with a Crickit and Circuit Playground Express coded in MakeCode.
