Hi,
Forgive the lack of technical language...
I have a reasonably straightforward project that I need some help with. I am creating a cinema room and I have a projector with a 12v trigger out which I am assuming sends a pulse out when it is turned on and a pulse when it is switched off. This is usually used to initiate the motorized projector screen up and down.
However, my projector screen does not have the 12v trigger adapter meaning I have no simple plug and play solution. Instead it has a 3-way switch connected to 110vac. Middle is off and rocking up or down raises or lowers the screen.
I want to take advantage of the 12v trigger on the projector and therefore need a relay for 110v that is triggered by the 12v pulse and cycles through the up and then down switch with a timed off happening after 1min or so...
Any relays or circuits you can point me to?
Thanks in advance...
