Arduino Based Piano with Recording and Replay
Arduino has been a boon for people who are not from the electronics background to build stuff easily. It has been a great prototyping tool or to try something cool, in this project we are going to build a small yet fun Piano using the Arduino. This piano is pretty much plain with just 8 push buttons and buzzer. It uses the tone() function of Arduino to create various types of piano notes on the speaker.
