Story

Step 1: Parts and Material

The Parts which we need are :

* Arduino

* Piezo Buzzer

* Push Buttons - 7

* Jumper Cables

Step 2: Connections

The Buttons are connected to D4 to D10 of the Arduino

The Piezo Buzzer -> D11 of the Arduino

Step 3: Play!

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 :)
