Reading a potentiometer by BARRAGAN

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.


int val; 

void setup()
{
  Serial.begin(9600);      // sets the serial port to 9600
}

void loop() 
{
  val = analogRead(0);     // read analog input pin 0
  Serial.print(val, DEC);  // prints the value read
  Serial.print(" ");       // prints a space betwen the numbers
  delay(100);              // wait 100ms for next reading
}
