Thanks for the replay.

HenrikOlsson,
That's what i was think excatelly, but it didn't hurt to ask.

HankMcSpank,
When a key is pressed AN0 go from 0-5v depend on the key pressed(ie; if 0 is pressed 0<AN0<.5V, if 1 is pressed .6<AN0<1.0V......).

Thank you,
Any other ideas or suggestions are appreciated.
