Ok, ive found an example that I may be able to use.
Does anyone know if i use the example at http://www.reifel.org/PICUserInterface/
If I replace the up button, with a microphone and the down button with a light sensor, remove the other two buttons, could this work??? Also would there be an alternative smaller pic i can use instead of 18F2620? I want to remove 3 of the 4 leds in the display, as i only need to display a small amount of data in one of the corners of the lcd.
I really hope someone can help, thank you for reading
