2021-05-30 (Su) Wearable Macro Keyboard BackOfTheHand BotH BLE HID

Getting a controller to work with a new protocol is often a trial, and I was relieved how well the ESP32 connected as a wireless keyboard. The credit goes to T-vK and their GitHub repo. They also provided libraries for ESP32 mouse and gamepad emulation. I found their page through an Instructable.

When I connected to my computer, my code kept closing windows because the last function was pressing escape with a light touch, then alt+F4 with a hard touch. The behavior was erratic, so I investigated and discovered that I neglected to connect Vcc to the central copper strip. The missing wire could also be the culprit behind my misbehaving IR sensors. Thankfully, I haven't removed them yet.

I tried some more testing on the infrared aerials, including increasing and decreasing the delay times. These devices have a feature/bug where they will fall back to a known level if they detect constant light sources, which is probably helpful for ignoring sunlight but not detecting a continuous HIGH signal.
