Post project 33: Car Battery Tester
Even though modern cars have a whole lot of technical and
electronic novelties on board, a simple indication of
the state of the car battery is often absent.
With the aid of a small circuit, using
a few transistors and LEDs, it
is simple to make such a thing
yourself.

This small, practical tester continually monitors the state of the battery in a car and indicates the battery voltage using a few LEDs. There are only three LEDs present, but that is sufficient to give a good indication, provided that each is set to show an appropriate voltage range.
