I am building a TV lift system for my flat screen TV. What I need is a trigger mechanism that will sense when I have turned on my TV, it will send a 12 volt signal to my relay that will run my linear actuators up and down. The relay will control the timing the actuators run, I just need a instant signal to start them in motion. Also when the TV if off, it will send another 12 volt signal.
Any ideas?
