/*
Analog input, analog output, serial output
Reads two analog input pins; a T000030 Jopystick Module Analog Sensor connected to I0 and I1, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) two T010111 LED Module connected on O0 and O1. Also prints the results to the serial monitor.
