Hello, I am looking to build a circuit for my car however I cannot figure it out on my own. I can describe what I want it to do any maybe someone can give me alittle info on it. From what I remember back in highschool electronics, this shouldn’t be too difficult. Thank you for your time.
Alright. I would like little blue LEDS that I place around or under the car to turn on when I shut off the engine and stay on for only 5 minutes. Ive seen it don’t before and I believe it uses a “relay” or something , yet I cannot remember how to do it. Somehow the circuit knows when the car’s accessories (I guess) are trigged off and on. I also need to know as much as possible for the job. I would like to use maybe 20 LED (few or less) and have them power off the car battery for the 5 minutes after I turn off the engine.
Thank you again for any help
