2021-04-15 (Th) Wearable Macro Keyboard BackOfTheHand BotH Microcontroller with Display

I picked a controller from my shelf with a screen, but I changed it for a different model on Amazon, hoping that it was more accessible for anyone who wanted to copy the design. The new board featured an ESP32 chip and a battery charging circuit. The ESP32 has Bluetooth, so it should work when I jump to a wireless design later.

I downloaded the Arduino libraries from the Amazon page and established a connection to the board. Next, I ran a "Hello World" example, then modified it to show different text.
