Question

Using the Energia software, as well as the Education BoosterPack MKII, what is the program/code that combines the input function of the joystick, using either the X or Y axis reading, and uses it to produce a tone on the buzzer, such that the buzzer tone varies in pitch when you move the joystick along whichever axis you have chosen? For example, if you have chosen the X axis to read, you should hear a low tone when the joystick is moved to the left, and should progress steadily to a higher tone when you move the joystick to the right.

Answer 1

#define X axis
#define Y axis
const int joystick Sel = 5;     
const int joystick X = 2;       
const int joystick Y =  26;    

       
int joystickSelState = 0;      
int joystickXState, joystickYState ;
int buzzerPin = 19;
int melody[] = { x axis ,y axis};
int noteDurations[] = { 4,2};
{
void setup() 
{ pinMode(buzzerPin, OUTPUT);
 }
}

void loop()

{

for (int thisNote = 0; thisNote < 26; thisNote++)

{

int noteDuration = 1000/noteDurations[thisNote];

tone(buzzerPin, melody[thisNote], noteDuration);

int pauseBetweenNotes = noteDuration + 50;

delay(pauseBetweenNotes);

noTone(buzzerPin);

}

}
