Code

When the sensor detects vibrations caused by tapping or knocking, the LED on pin 13 of the Arduino will be activated. Here’s a sample code sketch to achieve this functionality

//For more Projects: www.arduinocircuit.com
int Led = 13;	// LED on Arduino board 
int Shock = 3;	// sensor signal
int val;		// numeric variable to store sensor status
void setup()
{
	pinMode(Led, OUTPUT); 	// define LED as output interface
	pinMode(Shock, INPUT); 	// define input for sensor signal
}
void loop()
{
	val = digitalRead(Shock); // read and assign the value of digital interface 3 to val
	if(val == HIGH) // when sensor detects a signal, the LED flashes
	{
		digitalWrite(Led, LOW);
	}
	else
	{
		digitalWrite(Led, HIGH);
	}
}
