Light Sensitive Code

//Camille Kauffman
//excercise 5-4 from Getting Started with Arduino

const int LED = 9; // the pin for the LED
int val = 0; // variable used to store the value // coming from the sensor

void setup() {
   pinMode(LED, OUTPUT); // LED is as an OUTPUT // Note: Analogue pins are

}
 
 void loop() {
 
  val = analogRead(0); // read the value from // the sensor
  analogWrite(LED, val/4); // turn the LED on at // the brightness set
  delay(10); // stop the program for // some time
