Knock Sensor Module For 3pin KY-031 Percussion Knocking Knock Sensor Module Diy Starter Kit KY031
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);
