int Led=13;       // Define LDE Pin
int buttonpin=3;  // Define pin for touch sensor
int val;          // Define Variable val
void setup()
{
  pinMode(Led,OUTPUT);  // Define LED as output
  pinMode(buttonpin,INPUT); // Define touch sensor as input
}
void loop()
{
  val=digitalRead(buttonpin);// assign digital pin 3's reading to val
  if(val==HIGH) // anything detected by touch sensor, LED starts
  {
    digitalWrite(Led,HIGH);
  }
  else
  {
    digitalWrite(Led,LOW);
  }
