learn guide - https://learn.adafruit.com/neotrellis-soundboard/ This is a sound board using Adafruit’s NeoTrellis. This lets you trigger audio files so you can play it like a musical instrument. Each button can have different sounds so you can build your own sample kit. All of the electronics are housed in our 3D printed enclosure. The top and bottom covers snap fit so it’s easy to put together. It’s designed to be portable, compact device and it’s open source. In previous build we used several boards to make a similar project. For this one we can use Adafruit’s Feather and the Prop Maker Feather Wing. Check out the learn guide for documentation. You can follow along step by step to wire the electronics and build the assembly. Code on github https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/NeoTrellis_Soundbox CAD files https://www.thingiverse.com/thing:3750704 The software is written in Adafruit’s Circuit Python so it easy to program the hardware. We setup the REPL to print the file names and neopixel colors. This way we can verify the button mapping or catch any errors. The Feather shows up as a USB drive so you can edit the code directly on the device. All of the files live on the drive so it’s easy to change code on any computer. You Can Shake the device to shuffle the audio. Pressing the button on the side will reset the arrangement. We think it’s a fun demo of what you can with the accelerometer.
