Pin 1 is +5V, and Pin 3 is GND. Pin 2 is our output voltage.\nThe voltage our potentiometer outputs will be proportionate\nto how fast we want our motor to go forward.\nVLow = 0V\nVHigh = 5V

This voltage divider allows us to monitor the batteries voltage while \nit's running our electronics. Our VRef is a 5V reference, which means\nthe maximum voltage our ADC (Analog to Digital Converter) can read\nis 5V. Our batteries nominal voltage is around 7.4 volts, so we must\ntake the voltage down a bit so we can read it correctly.

REV_BTN, aka the forward button, sends a signal to our MCU\ntelling it that we should change our direction to forward. The resistor\nhere is a 10k pulldown resistor.
