Thanks guys!

I used the top example, and it worked perfectly!

I am now in the process of finding a way of adding a switch to enable the green led, the one that runs from the 5v.

If there is a simple way to this, please tell me because I'm unsure where to place it in the circuit.

Thanks again,

so how did you power the circuit? from a 9V batt or from the PC?

 

[tim_l_012]

well, all was well using 9V battery, until it ran out.
I decided the motherboard had constant power, tried to hook it up, started the PC, BANG, then dead.

I lost my hard drive and CD burner. Motherboard is fine though... :?

That was about 2 months ago, and all is fine now. A word of advice, use the power from the power supply, not from the motherboard. Now I am using the 5V red wire on the floppy power connector, and is working fine.

Thanks again,
