How to use a Vibration Sensor
Vibration / Shake Switch
Introduction
In this tutorial we will use one vibration sensor or shake switch to make a beep sound from a buzzer while we shake our breadboard.
What you will need - Hardware
For this tutorial you will need:
|
The Circuit
The connections are pretty easy.
The code :
Here's the code
*********************************************************************
/* Vibration Sensor (Shake Switch) - Testing with buzzer
In this tutorial we will use one vibration sensor (or shake switch)
to make a beep sound from a buzzer while we shake our breadboard.
*/
const int buzzer = 8; //Buzzer connected to pin 8 of Arduino uno / mega
int sensor; //Variable to store analog value (0-1023)
void setup()
{
Serial.begin(9600); //Only for debugging
pinMode(buzzer, OUTPUT);
}
void loop()
{
sensor = analogRead(A0);
//While sensor is not moving, analog pin receive 1023~1024 value
if (sensor<1022){
tone(buzzer, 500);
Serial.print("Sensor Value: ");
Serial.println(sensor);
}else{
noTone(buzzer);
Serial.print("Sensor Value: ");
Serial.println(sensor);
}
delay(100); //Small delay
}
