Parts

This project requires the Adafruit NeoTrellis M4 package. You will need a known, good USB A to micro-B cable to load software.

Other parts depend on if you'd like your project portable or not. You can select headphones or speakers. If you want portability, a cell phone recharge battery is ideal, otherwise you'll need 5V power for the speaker and for the NeoTrellis.

You can buy a pre-printed E is for Electronics coloring book or download a PDF later in this guide.
