### [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.
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).
