2019-10-28 (M) Electronic Wind Chimes EWC_Presenter

The faceplate was serviceable, so the electrical assembly could begin. Header pins had to be installed on the MIDI shield and Arduino Uno clone. Two pin pairs on the shield had to be tied together to run it in MIDI mode instead of a sound recorder.

There was also an amplifier on the MIDI shield capable of driving a couple of low-wattage speakers. I may never use them, but I installed the screw terminals for them, which barely cleared the power adapter from the Arduino.

The rest of the components installed with #6 bolts and nuts, and in the case of the potentiometers, a single nut-bolt combo with a fender washer between them.

A slew of wires was installed on the bottom of the shield and run to the components. One I/O pin was run to each tab on the keyboard in the hopes of creating an algorithm that would read each key independently. This is a solved problem, but I have not looked at the solution, and I will try to figure it out myself.
