This example shows how to use the tone() command to generate different pitches depending on which sensor is pressed.

==Hardware Required==

* Arduino or Genuino Board
* 8 ohm speaker
* 3 force sensing resistors
* 3 10k ohm resistors
* 100 ohm resistor
* hook-up wires
* breadboard

==Rangkaian==

==Code==

/*
keyboard

Plays a pitch that changes based on a changing analog input

circuit:
* 3 force-sensing resistors from +5V to analog in 0 through 5
* 3 10K resistors from analog in 0 through 5 to ground
* 8-ohm speaker on digital pin 8

#include "pitches.h"

const int threshold = 10; // minimum reading of the sensors that generates a note

// notes to play, corresponding to the 3 sensors:
int notes[] = {
NOTE_A4, NOTE_B4, NOTE_C3
};

void setup() {

}

void loop() {
for (int thisSensor = 0; thisSensor < 3; thisSensor++) {
// get a sensor reading:
int sensorReading = analogRead(thisSensor);

// if the sensor is pressed hard enough:
if (sensorReading > threshold) {
// play the note corresponding to this sensor:
tone(8, notes[thisSensor], 20);
}
