Arduino Basic Piano For Children (Pushbutton & Buzzer)

In Early ’90s Technology Was Limited and Worldwide there Were Few Electronic Toys. This kind toys with 8051 or plain common IC were easy to find. This particular project is not created by us. This project is shared by ExeCuteLi on hackster.io who deserves the full credit. Here is His Arduino Basic Piano For Children With Pushbutton & Buzzer as Components. The original project on hackster.io has video and detailed steps for full newbies :

We are sharing the project with our readers to encourage Free Software culture. We are encouraging to modify the project by showing our few older projects to make it more beautiful (although difficult). Those those are towards saying Arduino costs higher for this work, well there are cheap breeds from ATtiny family like ATtiny 10, ATtiny 13 which will work fine alone as microcontroller. However, working with ATtiny 10, ATtiny 13 will require minimum idea of working with bootloader.

Circuit and Code to Build Arduino Basic Piano For Children

You need the following components :

Arduino UNO or similar board
Pushbutton – Five
Buzzer – One
1K Ohm resister – Five
Jumpers – Few
Breadboard – One

---

Here is how the connection need to be made :

In our some earlier project, like Arduino door bell, you used a separate file for sound as pitches.h. Normally we need one .ino file in Arduino. That code is for this project this :

#include "pitches.h"
#define ACTIVATED LOW


const int PIEZO = 11;
const int LED = 13;

int buttonSong = 8;
const int BUTTON_C = 6;
const int BUTTON_AS = 4;
const int BUTTON_A = 3;
const int BUTTON_G = 2;


void setup()
{
  Serial.begin(9600);
  pinMode(LED, OUTPUT);
  pinMode(BUTTON_C, INPUT);
  digitalWrite(BUTTON_C,HIGH);
  pinMode(BUTTON_AS, INPUT);
  digitalWrite(BUTTON_AS,HIGH);
  pinMode(BUTTON_A, INPUT);
  digitalWrite(BUTTON_A,HIGH);
  pinMode(BUTTON_G, INPUT);
  digitalWrite(BUTTON_G,HIGH);
  pinMode (buttonSong, INPUT);
  digitalWrite(buttonSong, HIGH);
  
  digitalWrite(LED,LOW);
}


// notes in the melody:
int melody[] = {
NOTE_AS4, NOTE_C5, NOTE_AS4, NOTE_A4, NOTE_G4,  NOTE_C5, NOTE_AS4, NOTE_A4, NOTE_G4, NOTE_G4, NOTE_F4, 0, 0,
NOTE_DS4, NOTE_DS4, NOTE_F4, NOTE_D4, 0, 0, 0, NOTE_D4, NOTE_D4, NOTE_D4, NOTE_D4, NOTE_D5, NOTE_D5,
NOTE_G3, NOTE_AS3, NOTE_C4, NOTE_G3, NOTE_G3, NOTE_AS3, NOTE_AS4, NOTE_A4, NOTE_A4, NOTE_A4, NOTE_AS4, NOTE_AS4, 
NOTE_G3, NOTE_AS3, NOTE_C4, NOTE_G3, NOTE_G3, NOTE_AS3,


NOTE_AS4, NOTE_C5, NOTE_AS4, NOTE_A4, NOTE_G4,  NOTE_C5, NOTE_AS4, NOTE_A4, NOTE_G4, NOTE_G4, NOTE_F4, 0, 0,

Now compile and run it.

Can you improve the project by adding one LED for each pushbutton so that upon pushbutton press they’ll light up? We have such kind of guide for creating keypad tone for making LED on upon pushbutton press.
