2PCS KY-031 3pin Percussion Knocking Knock Sensor Module for Arduino PIC AVR for Raspberry pi DIY Starter Kit KY031

Description

• 2PCS KY-031 3pin Percussion Knocking Knock Sensor Module for Arduino PIC AVR For Raspberry pi Diy Starter Kit KY031

100% brand new and high quality
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);
}
else
{
digitalWrite(Led, HIGH);
}
}
Package Included:
1 x Knock Sensor Module with LED KY-031 For Arduino PIC AVR FOR Raspberry pi
