Push a button, it plays a sound!
In this project, the Trellis triggers samples on an Adafruit Audio FX soundboard. The Pro Trinket interfaces between the two over serial and i2c and ties the samples to the buttons.
It's a really slick way to make a compact, all-in-one sound board. This version of the Audio FX Soundboard features a built in amp so you can wire speakers up to terminals or directly on the board.
Whenever a Trellis key is pressed, there's a loop in the arduino sketch that listens for button presses and plays back a sample from a list.
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!
