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.
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.
Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Since then Adafruit has grown to over 25 employees in the heart of NYC. We've expanded our offerings to include tools, equipment and electronics that Limor personally selects, tests and approves before going in to the Adafruit store. We pride ourselves on having great prices, the best customer service, technical support and fast shipping. We hope we can assist you on your journey of learning - At Adafruit we celebrate engineering happiness!
