2023-09-24 (Su) EWC_Cyberdeck Arduino sketch started

I connected the hardware to a USB port, and the voltage display came on immediately, showing close to five volts. When I tested for power, the headphone adapter seemed like a problem, but I traced that down to a bad cable.

I updated the schematic with the notes from yesterday and included wire colors, which I did not use at home because my wire selection was limited to whatever I had on hand.
Updated schematic

I opened my code from Keyboardolier, which had IO expanders and addressable LEDs. The program did not find either, but I updated the sketch to look for the correct I2C addresses and use the right pin for the lights.

Except for one column, all the buttons worked! To help fix the row, I programmed the light bar to turn on a green light based on whichever row I hold a switch. The button returns to a default color based on the paint job when I release it. I chose purple light for the black areas.
All aglow
