Relay

I solved my problem with the 5V working but not the pin. I still don't know why it does this but I've bypassed the problem. Insted of trying to get power strait from the pin I will put a relay in the circuit and operate the relay using the pin. This also means that I am able to test how fast I can cycle the laser. I figured out that I can cycle it on and off once every five one-thousandths of a second.
