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