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.
  • Connect one pin of vibration sensor to Arduino Analog pin A0 and the other to 5V pin.
  • Now connect the buzzer, one pin to Arduino pin 8 and the other to GND.

/* 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
}
Download the code from here and open it with Arduino IDE. Open the serial monitor from tools menu of Arduino IDE to test it.
