Hi all, I don’t know where to start with this one but once i have a general plan of attack things normally work out ok!!
I need some help with the basic wiring for a Nano, there’s lots of examples of single PIR setups but very little on dual detectors.
Basically i have put a 12v PIR at the top of the stairs and this works fine but the downstairs landing turns right so the PIR at the top only detects you after you’ve run the gauntlet in the dark at the bottom.
At the moment i’m just using the 12v in / 12v out to LED detectors from Ebay but there doesn’t seem to be a way of parallel operation.
I have all the equipment needed to do it with an Arduino, i really do want to keep it compact so the Nano is a must, two PIRs, LEDs already run but can easily run the additional wiring for the second PIR.
Any help with the wiring layout , code for two PIRs or any other ideas will be greatly appreciated.
Big thanks, John
