Having designed a vertical lift box to house my AV projector i have added a 12v servo that operates simply with the poles wired to go forward and then reversed to drive servo back. Now I am aware that the trigger from my projector only gives a pulse signal and insufficient amperage to drive the servo but I would like to put a relay that does the switching as a above but a little flummoxed. I assume that when the BenQ projector is powered down the trigger pulses again?
