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 to the serial monitor
int sensorValue;
void setup ()
{
Serial .begin (9600);
}
void loop ()
{
sensorValue = analogRead (0);
Serial .println (sensorValue, DEC );
delay (100);
}
