Description

knock sensor module and a digital interface, built-in LED build a simple 
circuit to produce percussion flasher.
Interface comes with digital LED, will knock sensor connected digital 3
interface, when percussion sensor senses measure to percussive signals, 
LED flashing light.

Routines source code:
int Led = 13;// define LED Interface
int Shock = 3;// define the percussion Sensor Interface
int val;// define numeric variables val
void setup ()
{
   pinMode (Led, OUTPUT) ;// define LED as output interface
   pinMode (Shock, INPUT) ;// define knock sensor output interface
}
void loop ()
{
   val = digitalRead (Shock) ;// read digital interface is assigned a value of 3 val
   if (val == HIGH) // When the percussion when the sensor detects a signal, LED flashes
   {
      digitalWrite(Led, LOW);
   }
   else
   {
      digitalWrite(Led, HIGH);
   }
