Hello everyone, I have a project that I keep getting stuck with on. Here's what I'm trying to do...
I need something to act as a trigger when this project is exposed to average room lighting.
The project is a 12vdc system that once triggered needs to power a car alarm siren. My first idea was to use a relay, looping the power out also back into the relay so that once it was tripped it would hold itself closed, and I still think this would work fine, but I'm hitting a road block on how to make the trigger.
I'm pretty much a noob when dealing with photocells, but I don't think they can stand up to 12vdc.
Any ideas are very much welcomed as I'm in the weeds at this point.
I can pretty much buy what I need as long as its not too pricey.
My project is going to be in a box, and when it's opened and light hits it, it needs to let power flow to my siren which is 12 vdc @ 1.25A
Thanks!
