Voltage monitor for car’s battery and its charging system

Posted on Tuesday, October 11th, 2011 in hacks by DP

Raj designed a car battery volt-meter. The core of the project is a PIC16F1827 which uses its internal fixed voltage reference FVR and ADC to precisely measure the battery voltage. Measured voltage is displayed on a 4 digit 7 segment display. His circuit is connected to the car’s battery through a standard car lighter jack.
