Hi guys.

I wanna make a keyboard by myself. Unfortunately I am a beginner of electronics.

The keyboard should be connected to a computer by USB like normal keyboards.

However, this keyboard should only consist of 16 square-shaped buttons, arranged in 4x4.

It is actually a controller for games. (A music game called Jubeat if you have heard about it)

You may consider each button corresponds to a certain button on normal keyboards individually.

I have no idea about the simplest way to make such things as I know nothing about circuits for computers.

Could I have some hints on that please?

Thanks a lot buddies!

 

You do realize that you can pick these up for under $10?
