# NeoTrellis Sound Board
## Overview
https://youtu.be/cZw4cC1Hbns
## Sound Board with Prop-Maker
Use an Adafruit Feather M4 and Prop-Maker FeatherWing to make a portal NeoTrellis soundbox! Play and trigger motion activated audio samples with CircuitPython. Build and assemble the 3D printed enclosure to make your own with built-in speaker and rechargeable battery!
Each button has its own NeoPixel so you can make them any color. Assign audio wave files and set custom triggers for loops and latching using python code. Use the accelerometer to detect shake to shuffle the playlist or trigger motion activated sound effects.
## CircuitPython USB Drive
Use microUSB port to update the **code.py** file, drag and drop audio files on to the circuit python USB drive. Recharge over USB with Adafruit Feather's built-in battery charging circuit.
