Introduction

This is a knock sensor module. When you knock it, it can send a momentary signal. You can combine it with Arduino to make some interesting experiment, e.g. electronic drum.

  • Working voltage: 5V

Sample Code

int Led=13;//define LED interface
int Shock=3;//define knock sensor interface
int val;//define digital variable val
void setup()
{
pinMode(Led,OUTPUT);//define LED to be output interface
pinMode(Shock,INPUT);//define knock sensor to be output interface
}
void loop()
{
val=digitalRead(Shock);//read the value of interface3 and evaluate it to val
if(val==HIGH)//when the knock sensor detect a signal, LED will be flashing
{
digitalWrite(Led,LOW);
}
else
{
digitalWrite(Led,HIGH);
}
}


Upload the code to the board. When the sensor detects a knock signal, both the led on the sensor and led 13 on the UNO board are turned on.



Extension

You can extend to connect an external LED; when knock the sensor, the external LED will turn on. For example:
