Add a headphone jack and upload the following code to arduino
#include <Tone.h>
Tone mytone; // declare a tone name
void setup() {
// initialize the tone
mytone.begin(8);
}
void loop() {
// read the analog input
int inVar = analogRead(0);
// map the input to a frequency range between 200 and 2000 Hz
int note = map(inVar, 0, 1023, 200, 2000);
// play the note
mytone.play(note);
}
