int Led = 13 ;/ / define LED Interface
int buttonpin = 3; / / define Metal Touch Sensor Interface
int val ;/ / define numeric variables val
void setup() {
  pinMode(Led, OUTPUT) ;/ / define LED as output interface
  pinMode(buttonpin, INPUT) ;/ / define metal touch sensor output interface
}
void loop() {
  val = digitalRead(buttonpin) ;/ / digital interface will be assigned a value of 3 to read val
  if (val == HIGH) { // When the metal touch sensor detects a signal, LED flashes
    digitalWrite(Led, HIGH);
  } else {
