// ! First we will test the value of the LED to see if when we press the button we can read LED's state
// ! If successful, we'll then see if we can read when the button is pressed
// ! Third -> we can test if we're able to toggle the button via GPIO, which would require changing pinMode to digitalWrite

// TODO: bridge grounds of arduino and board; make the mosfet circuitry, bridge inactive USB port to fool circuitry
