        RA4 is open collector which means it can only pull a line DOWN, not up to
5V. You have to put a pull up resistor on it for it to function as you want,
however be aware of the value, if it's to low you risk drawing to much from
th PIC, if it's to high you have to be careful about read-modify-write
operations on port A. TTYL
