Hi all,
I have just made a project that displays the temperature from two sensors on a LCD display . My doubt is ,since the circuit is designed to work on 12 v batteries ( 2 x9v batteries in series limited by a LM7812 ic) , Can it be connected to a car battery without any modification or will the high amperage car battery blow up the components.
My friend tells me that the system will draw only the required amps from the car battery is this true ?
thanks
