Reading a potentiometer
by BARRAGAN <http://barraganstudio.com>

Reads values from a potentiometer connected to the analog input pin 0. The value read from the sensor is proportional to the knob position on the potentiomenter. The value read is printed through the serial to be monitored using the serial monitor.
