2019-10-23 (W) Electronic Wind Chimes EWC_Presenter

The Electronic Wind Chimes have been a lot of fun to build and I want to start leveraging them for more ambitious purposes. In the next model, I will have the same features as the EWC_Handheld, but it will have additional capabilities. Most notably, there are more buttons, and these will be a simple soundboard like the Little Drummer Bot but without velocity sensing. The purpose of this build will be to create background music for PillarGame at the IoTHackDay. With luck, I will be able to program multiple instruments that gradually ascend from calm ambient sounds to a hectic assembly without the player noticing the change.

Enough background
The keypad was a surplus store find, as well as the MIDI shield and slider pot. Due to size, the buttons were the central focus for this project, followed by the two sliders. In an earlier BOM, this project used an Adafruit Feather, MIDI Featherwing, and a rechargeable battery, but this was updated to a knock-off Uno with a shield. All the relevant measurements were recorded, so a faceplate could be designed for a laser cutter.
