Computer controlled switch? Answered
I am looking to close a circuit using software on my pc, and if possible through the network but worse case I can connect to a specific pc.
I have a door mechanism that opens when a certain circuit is closed, so I want to be able to control that door from my office. I can do any wiring or add a circuit board to a pc that about 15 feet away.
I was thinking some kind of circuit board, or even splicing into a serial port or parallel port and connecting that to the PC. Then on the PC i would need some kind of program that all it would be is a button that when I press it, the circuit is closed, either for the duration I'm holding down the button, for a certain amount of time after the button is pressed or anything really.
I'm no electrical engineer of software programmer, but I have a base understanding. I am in IT and know how to solder and basic programming.
My ultimate solution would be some logic board that has an RJ-45 connection that I can give an IP address so I can open the door from any computer on the network and two pins/connections out to close the circuit. Sending a command to the board from command line would be just as well as a small program that displays a button.
Thanks in advance.
