#1654: Percussion Knock Sensor Module (KY-031)


 Knock sensor module and a digital 13 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);




   digitalWrite(Led, HIGH);
