Capacitors are one of the most common passive electrical components that are extensively used in all kinds of electronic circuits. In this project, we will discuss a technique of building a digital capacitance meter using a PIC microcontroller. This project can measure capacitance values from 1 nF to 99 μF, with a resolution of 1 nF. The technique is based on measuring the time elapsed when a capacitor is charged to a known voltage through a series resistor. The idea of measuring the time elapsed when the capacitor is charged from 0 to a known voltage can be implemented with any microcontroller. Here, we are using the PIC16F628A microcontroller, which has two built-in analog comparators. This project uses the Analog Comparator 2 and TIMER2 modules to determine the time elapsed during the charging process of the capacitor.
Voltage across a capacitor builds up exponentially and is a function of RC time constant.
