All you need is some capcitors some resistors and one tiny NE555P IC.

and of course this PCB board.

This is just a fun project that emits tones of different frequencies. The change in resistance decides makes the Ic emit diifferent tones.

This board contains 8 push buttons and 8 resistors.

In the v2 I will add a variable resistor and many other components too.

You can use upto a nine volt battery for this piano and you are free to use this on any of your projects.

That's it .. i am not much of a talker. You know everything .... its a small project . Anyway my keyboard got burned and i am using a very old one so I dont feel like typing

Oh! and please check out my channel : www.youtube.com/innovationtech

(the picture is clickbait dont tell me you belived it)

If you buy this PCB it will be a great help to me since I require funds for my research in Electronics. My parents buy me the normal modules and all that. But I need a bit more to buy a raspberry PI4.

Thank you if you read this :)
