Glowing piano keys

[clemence]

Hi guys,

It's a piano with guiding lights. I plan to build a piano with glowing key for kids. So the key will lights one after another to guide the kids playing pre programmed songs.
So the key needs to light after certain key pressed, if the wrong key was pressed then the next "correct" key won't light.
any idea how I could do this?

Many thanks!

I have seen commercial retail models that do this. Perhaps look in a piano store and convince the salesman to show you the inside bits.

Can you give me the link to that? Thank you
