errors, and you can upload the code.

//Rotary controls LED

int rotaryPin = A0; // select the input pin for the rotary

int ledPin = 4; // select the pin for the LED

int rotaryValue = 0; // variable to store the value coming from the rota

void setup() {

// declare the ledPin as an OUTPUT:

pinMode(ledPin, OUTPUT);

}

void loop() {

// read the value from the sensor:

rotaryValue = analogRead(rotaryPin);

// turn the ledPin on

digitalWrite(ledPin, HIGH);

// stop the program for <sensorValue> milliseconds:

delay(rotaryValue);

// turn the ledPin off:

digitalWrite(ledPin, LOW);

// stop the program for for <sensorValue> milliseconds:

delay(rotaryValue);
