Hi everyone!
I know it's already a thread about PP, but I'm having different troubles. I have made the newbie arrangement, diode, transistor, relay, load, and It's freaking me out:
Please:
1. Why does the PP fire random signals during system startup? There is some way to prevent that? (instead of disconnecting the port, ofcourse)
2. Can I receive signals through parallel port? According to almighty google yes, but it talks about complex circuits, I just want to know the state of a microswitch in my door
3. Why, if more than three "pins" are ON (I mean, firing 5V), the program goes lazy and cease to respond until I turn them off? Is this a programmer fault, or actually the PP has a limit of maximum "pins" active?
Thank you so much in advance!! My DIY proud is on the floor, and I don't want to switch to serial port yet
