Grove - Buzzer

This project will output sound to a Grove Buzzer whenever a Grove Push Button is pressed.

  1. Connect a Grove Push Button tto a grove connector on your board and a Grove Buzzer.
  2. Begin a new Grove project using the Grove Project Import method at the bottom of this page.
  3. In the Project Explorer on the left, under Sources, double click to open the file "arduinoApp.cpp".
  4. Copy and paste the following code into this file to replace it's contents:
//--------- Buzzer Test
#include "arduinoApp.h"

int speakerPin = 6;                  // Grove Buzzer connect to this pin
int inPin = 4;  // pushbutton connected to this digital pin number
int val = 0;    // variable to store the read value

void setup()
    pinMode(speakerPin, OUTPUT);
    pinMode(inPin, INPUT);

void playTone(int tone, int duration) {
    for (long i = 0; i < duration * 1000L; i += tone * 2) {
        digitalWrite(speakerPin, HIGH);
        digitalWrite(speakerPin, LOW);

void loop()
    val = digitalRead(inPin);   // read the input pin
        playTone(1915, 500);

  1. Select Project from the main menu and choose Build Project.
  2. If there are any errors they will be displayed in the Problems tab.

Now follow the steps under Debugging your ARM Board Project.
