Hi!
I am wondering if this will work, and dont want to destroy anything trying,,,
i know theres products out there that do this, but I want to make my own...
Through software I can control turning on individual pins out my parallel port.. The switch on my remote basically just closes the circuit for that particular button.. I want to know if the voltage going through the remotes button when closed (5v) matches the voltage comming out of my parallel port (which it does), is there a way I can wire in my parallel port to activate the button through software?
So one end of the switch has 5v, and the other has nothing until the switch is pressed.. Can I just wire in the data line of my parallel port to the end of the switch that is doing nothing. Then when I turn on that data line +5 will go and the remote will think the button was pressed and act accordingly?>
Do I need to tie the ground out the parallel port to the ground on the controller?
thanks for your help
