Grove - Buzzer

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

Connect a Grove Push Button tto a grove connector on your board and a Grove Buzzer.
Begin a new Grove project using the Grove Project Import method at the bottom of this page.
In the Project Explorer on the left, under Sources, double click to open the file "arduinoApp.cpp".
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);
        delayMicroseconds(tone);
        digitalWrite(speakerPin, LOW);
        delayMicroseconds(tone);
    }
}

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

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

Click the Browse button next to "select root directory". Find the directory where you installed the Axiom ARM Support Software and select the sub-directory: Source\Grove.

Click the OK button and you will see a list of Projects, one for ecah Axiom ARM board with Grove support. Check the project that matches the name of your board. So if you have the AXM-0702-CM-K60D board click on the box next to the CM-K60D project.

Under Options, check "Copy projects into workspace". Click the Finish button

You should now have a new project with the name of your board. To rename the project:

Right click the project name on the Project Explorer on the left then choose Rename...

Type the name you want for your project and click OK

Right click the project name again and choose Properties

Under C/C++ Build / Settings select the Build Artifact tab
