2023-04-27 (Th) PhoneRobot Additional hardware

On top of the malfunctioning touch emulator, I needed to wire up the light ring. I chose individually addressable LEDs for greater flexibility because they run at 5V and one signal wire. I kept the conductors tidy and added Adafruit's Neopixel library to my code. I wrote a function to turn all the lights red, green, then blue. Even at 2%, the lights are easy to see.

I searched for a micro USB cable with data lines, a trial, because many of mine were power-only. I connected it to the auto-clicker, mapped the wires, and soldered them to the PhoneRobot. I joined the GND connections and intercepted the signal wire to control it with the Arduino. I added a 1KΩ resistor between my output and the breakout board to protect the circuitry in the touch emulator. To use the emulator, I need to run the auto clicker, the speed is irrelevant, and enable output 12 on the Arduino. All tests were successful.
