Here I have made Arduino piano keyboard using pushbutton pins. I have included the original piano notes here.

In this project, I have used an Arduino to make a piano with the proper piano notes. Here I have used the tone function to set different frequency of piano in the Arduino sketch so you can play the eleven different notes of a piano through this Arduino piano. Though it does not have an original piano feel, you can feel that how would it match up with the Arduino keyboard.
