I've built a simple push-button starter for my car, based off a DEI remote car starter. Basically, it operates the program when the remote starter sees two pulses from the button. This is the easy part...
But when I want to run accessories WITHOUT starting the car, I want to build a type of timing device/relay that ONLY activates the accessory circuit latch relay when it sees a steady, 2 second trigger from the same 'start' button.
And on the same note, I need the same timer to turn OFF the accessory circuit thru the (latching)relay when it sees another 2 second trigger hold...
Thankfully, the remote starter ignores this signal, and only operates on two quick pulses.
But this timing device HAS to ignore any other pulse triggers from the same button...I need it to only operate when it is held for 2 seconds.
The latching relay hooked up to this uses two positive inputs...one to close the circuit, the other to open it, which no doubt, complicates matters.
Can someone please help?
Thanks
