Car Battery Monitor with 3 LED

Car battery monitor schematicCar Battery Monitor circuit description:
This is a circuit diagram of the 3 LED bar graph type battery monitor ideal for monitoring the voltage level of the car battery voltage with battery.

When the battery voltage is 11.5V or less transistor Q1 is turned on and the LED D1 will be bright. When the battery voltage is between 11.5 and 13.5 V, the transistor Q2 is turned on and the LED D2 will light up. When the battery voltage is 13.5V transistor Q3 will be on the D3 and the LED will light.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
