Title: Analog and Digitale
Post by Titus on 09/16/07 at 13:11:29
hi there,

I asume there was a reason for creating more digitale i/o ports then analog.

But i wonder why.

If i needed lets say 20 analog ports.
Would i need an AD converter or what?

Those photo resistors, they are analog.

can you hack a digitale port and convert it to analog?
