Hi all,

I am using a menu in my LCD where 3 buttons are used, one to scroll up, one to scroll down and the other to select.

Is it possible to use a scrolling wheel (like the one in a computer mouse) instead of three buttons ? if yes, where can i buy one from?

Thanks

 

Hello,

Older non optical mice? have wheels that when you spin the mouse wheel it pulses incrementally..

So yea i can see that working for you w/ minimal pain,newer ones use IR led interrupters,could possibly have issues driving it.

Far as where to find old school ball mice..no place is going to beat Ebay.

There is a few other vids that fully explain encoders and even a few that do exactly what you want.
