Custom Music Player and Electronic Piano:

You can find a Mini Electronic Piano as well as Custom Music player in this following instructables.

Step 1: Parts and Material (For Piano)

The Parts which we need are :

* Arduino

* Piezo Buzzer

* Push Buttons - 7

* Jumper Cables

* Arduino MP3 Shield x 1

* Speaker: 3W, 4 ohms x 2

Step 2: Step 2: Connections (For Piano)

The Buttons are connected to D4 to D10 of the Arduino

The Piezo Buzzer -> D11 of the Arduino

Step 3: The Code (For Piano)

Before you can start playing your piano, you will need to obtain and install the Tone Arduino library if it is not already installed. This can be downloaded from Github here. If you do not know how to install third-party Arduino libraries in your version of the Arduino IDE, reference this guide on Arduino.cc. Attached below, you will find a zip file that contains the Arduino code for Arduino Piano. Download it and unzip it somewhere on your computer. Open Arduino_Piano.ino in the Arduino IDE and upload the code to your Arduino.

Step 4: Play! (For Piano)

And that's it! You should now be able to tap on the keys and hear the corresponding notes played through the buzzer. If the note isn't accurate, you can adjust the note value in the Arduino sketch to set what value that the pitch is achieved.You can also change the scale that is played by uncommenting one of the few scales included, or make your own scale! If you make your own piano, please comment and show us some pictures and videos. We'd love to see some creative instruments!

Give a thumbs up if it really helped you and do follow my channel for interesting projects :) Thanks for reading!

Step 5: Hardware (For Custom Music Player)

I had cut the Plywood to the required dimension and Glass to cover each RGB LED Panel.

The 12V adapter is installed for powering the device and a separate adapter is used to light the LED Panel. The Relay Connections are used to switch the LED Color Panels. Make sure that the supply is isolated. Drill the plywood to mount the PCB.

Step 6: Connections (For Custom Music Player)

*Arduino -> BT MODULE*

TX -> RX

RX -> TX

VCC -> 3.3v

GND -> GND

*Arduino -> Relay Board*

IN1 -> A1

IN2 -> A2

IN3 -> A3

IN4 -> A4

IN5 -> A5

IN6 -> A6

IN7 -> A7

VCC -> VCC

GND -> GND

*Arduino -> MP3Module*

TX -> D10

RX -> D11

VCC -> 3.3v

GND -> GND

Step 7: The Code(For Custom Music Player)

You can find the sample code below.
