2021-04-22 (Th) Wearable Macro Keyboard BackOfTheHand BotH Arduino Pull-down Resistors

I wrote a short program to check analog values and print them to the computer. At first, they all showed 1023, their maximum value. I could pry up the finger rods and lower the number, but I couldn't get lower than 980Ω, which the computer showed if I separated the connection. I decided to add pull-down resistors to each circuit, but I wasn't sure which size resistor to use, so I added four different values. At high resistor values, like 47KΩ or 10KΩ, I could detect differences, but the low values, like 220Ω produced the starkest value swings.
