Hi all
I'm looking to control some devices from my computer. I've decided to play around with the parallel port.
I've gotten this advice from somebody.
================================================================== Output multiplexer for parallel port:
I've very intersted in doing this, as I'm looking to control 100+ devices. For starters I'm just looking to switch some LED's on and off after the 373's. I'm not sure what mosfets to use and how exactly to tie them into the diagram mentioned above. In the end I'm wanting to switch 1 amp.
Eventually I'm going to also want to add in a continuity check (LED that operates on less than 50 milli amps) on each of the connections to the switching device after the 373. I'm probably going to be placing some sort of terminal block in there for easy connection.
Any advice is appreciated.
