Description

In this project we are going to make a **PIC based Car Battery Monitoring system on PCB**. This Car Battery Monitoring Circuit is used to monitor the power of Car Battery by just plugging it into the power outlet on the dashboard of a car. The PCB also has the option to use it as **Voltage Measurement tool or Voltmeter** without using USB car charger. We have attached a terminal block here to measure the voltage of other power sources, just by connecting two wires in it from the power source.
