Product description

Product Description :

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.

Size: 30x18x6mm (approx)

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);
