Arduino

int adcPin = A0; // select the input pin for the potentiometer
int ledPin = A1; // select the pin for the LED
int adcIn = 0;   // variable to store the value coming from the sensor
void setup()
{
    Serial.begin(9600); // init serial to 9600b/s
    pinMode(ledPin, OUTPUT); // set ledPin to OUTPUT
    Serial.println("Sliding Potentiometer Test Code!!");
}
void loop()
{
    // read the value from the sensor:
    adcIn = analogRead(adcPin);
    if(adcIn >= 500) digitalWrite(ledPin,HIGH);  // if adc in > 500, led light
    else digitalWrite(ledPin, LOW);
