Picture of Simple Electronic Piano with 555 timer in CD Case
In this instructable, I will show you how to make a simple electronic piano with common components. It uses capacitors and resistors, so you could easily modify the circuit. When the project is finished you will have a working simple circuit that can produce a variety of tones.

Of course, there are a couple of instructables that already feature such a circuit, but this is an Electronic Piano similiar to the one designed by sholtob. For reference, the original sholtob article is here while a great tutorial on building it is here. For the enclosure I used an old CD case, so it will easy to hold, and to keep the circuit well.


This is the video of my electronic piano
