Did I miss something?

If you use a PIC you just use the internal pull up resistors and 5 switches bringing each respective port to ground when pushed, you take a reading once every minute and write the 5 bits status to the PIC's flash. When you are done you just read the PIC's flash.I thought about that, but PWM-out to create an analog voltage level might be a problem.
