a) To be run upon initialization (i.e. implement this in the setup() function)

• Initialize the development board

• Sound the buzzer

• Write the message “ACCELEROMETER” on the LCD screen.

• Wait two seconds

Answer 1

#include <Wire.h>
#include "MMA7660.h"
MMA7660 accelemeter;
int buzzer  = 10;
void setup()
{
	accelemeter.init();  
	Serial.begin(9600);
	Serial.println("ACCELEROMETER: ");
}
void loop()
{
	tone(buzzer,261); 
	int8_t x;
	int8_t y;
	int8_t z;
	float ax,ay,az;
	accelemeter.getXYZ(&x,&y,&z);
	
	delay(500);
	tone(buzzer,261); 
}
