Arduino Tutorial: Mini Piano
In this video, I show you how to make a mini piano using Arduino.
Step 1: Parts and Material
The Parts which we need are :
* 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: The Code
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!
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!
