Use the LED comes with digital pin 13, and connect the shock sensor output to digital pin 3, when the shock sensor senses vibration, LED will blink.



int Led=13;



int Shock=3



int val;



void setup()



{



pinMode(Led,OUTPUT);



pinMode(Shock,INPUT);//



}



void loop()



{



val=digitalRead(Shock);



if(val==HIGH)/



{



digitalWrite(Led,LOW);



}



else



{



digitalWrite(Led,HIGH);



}



}
