2021-07-06 (Tu) Wearable Macro Keyboard BackOfTheHand BotH

I had trouble knowing if I pressed a button since there was no feedback except through the serial port. I added a few lines to activate the vibrating motor whenever I press a button, and later I added a bit to suppress the buzzer in certain circumstances.

I spent most of the day integrating the accelerometer. I can adjust the system volume by twisting my wrist like a motorcycle throttle whenever I hold a button. Twisting is helpful because it is a natural motion, and it only requires a single button to adjust up or down. I ran into problems with the vibrator overstimulating the accelerometer, which is why I added the override to keep it still.

When I adjusted the volume on my phone, it was touchy compared to a PC. A PC usually increments or decrements by two each time the volume up or down is pressed so that it can go from zero to one-hundred in fifty presses, but an iPhone only recognizes sixteen levels. I added a multiplier to make it manageable, but I will have to make it possible to adjust it through on-screen settings later.
