# Adafruit projects ## Arduino Sketches ### [ItsyBitsy 32u4 5V](https://www.adafruit.com/product/3677) & [Adafruit Audio FX Mini Sound Board](https://www.adafruit.com/product/2342) & [Trellis](https://www.adafruit.com/product/1616) First incarnation of a soundboard inspired by Adafruit's [Portable Trellis Sound Board](https://learn.adafruit.com/portable-trellis-sound-board/overview). The originally suggested microcontroller in the project was the [Pro Trinket 5V](https://www.adafruit.com/product/2000), but since Adafruit itself advised against using that board, I replaced it with an [ItsyBitsy 32u4 5V](https://www.adafruit.com/product/3677). The code for that version can be found [here](https://code.spamasaurus.com/djpbessems/Arduino.Sketches/src/branch/master/Itsybitsy-32u4-5V_Trellis_Audio-FX-Soundboard.ino). Sadly, this version died soon after it came to fruition, most likely due to an open window in rainy weather. ### [Feather M4 Express](https://www.adafruit.com/product/3857) & [Featherwing Music Maker w/ Amp](https://www.adafruit.com/product/3436) & [NeoTrellis](https://www.adafruit.com/product/3954) Second incarnation of the portable sound board. In my search for replacement parts, I got enamoured with the elegance that is Adafruit's [Feather M4 Express](https://www.adafruit.com/product/3857) along with the huge range of [FeatherWings](https://www.adafruit.com/category/871) that can be stacked on top. Since the original Trellis can only use single colour LED's (*Though I did mix different coloured leds in the first version of my sound board*), and Adafruit enticed me with 24-bit colour LED's, I was eager to upgrade to the [NeoTrellis](https://www.adafruit.com/product/3954). As an added benefit to these upgrades, the [LiIon/LiPoly Backpack](https://www.adafruit.com/product/2124) became superfluous... The code for this most recent version can be found [here](https://code.spamasaurus.com/djpbessems/Arduino.Sketches/src/branch/master/Feather-M4-Express_NeoTrellis_Music-Maker-FeatherWing-w-Amp.ino). ## CircuitPython
