High Impedance DC Voltmeter

This is a project schematic for voltmeter circuit. This circuit is using digital system. This circuit is based on LM324 single chip IC. Here’s the figure of the circuit.


This circuit is of a comparator circuit, can be measured with a step 1Volt, car battery voltage. Hint voltage to the battery voltage ratio, which is applied to the inverting input of the amplifier, with a reference voltage produced by the diode D1, such as the current value so good thermic stability. With the RV1, we set the voltage gradient that we want. In this circuit is to use a type LM324 comparator.
