Hi everyone,
I am doing project using many chips and parallel port to run fan

But the problem , our circuit it doesn't run when we provide the voltage
We didn't use parallel port yet because just we want to test the circuit if it is work?

The last time I checked, Arduinos don't have parallel ports.  Are you certain you are posting your request for help on the correct forum?  Could you have meant your posts for a "PC automation" forum?
