Hi
I am looking for a solution or a small device that can help me close or open an electric circuit with USB.
What I mean: I got led strip that get power from my car plug. It stay open all the time since the car plug always working even if the car is not running. But O also got a USB port that is close when the car is stopped. So I want to use the USB as a power controller for the led strip and open the circuit when the car is running and close it when is stop. The led strip will get it electrical power of 12v from the car power plug but the USB will control the circuit.
Does anyone got an idea or can build this kind of small device?
Thanks
