Thats not so bad then, Im not sure what the rest of it does.

BTW, i do have a brain but its not working today! I didnt get to bed till 7:30 this morning then my dad woke me up at 12:00 to figure out why all the text on someones PC was too small. Ive replaced the beer with coffee but its still not enough.

I forgot about using a cap/resistor. Im sure i can squeeze them in somewhere.

The best place to connect the inputs is on portb. Ive checked the datasheet and it says those pins have the diodes so that should be fine.

I have got some safety glasses but i usually only use those for woodwork
