/*
Analog input, analog output, serial output

Reads an analog input pin, and T000150 Linear Potetiometer Analog Sensor connected to I0, maps the result to a range from 0 to 255
and uses the result to set the pulsewidth modulation (PWM) on a T010111 LED Module connected on O0.
Also prints the results to the serial monitor.
