Overview

We don't need any snow to build this awesome snowman.

We just need some foam balls, stiff wire, festive decorations, a Circuit Playground Express (CPX) with CRICKIT, a servo motor and some extra electronic goodies.

To make this snowman dance, just touch the top of his hat! This triggers a servo in his belly that moves his body around.

This guide will show how to program this groovy guy using Microsoft MakeCode, an easy to use block-based programming system.
