In this post I will show how to construct a digital capacitance meter circuit using Arduino which can measure capacitance of capacitors ranging from 1 microfarad to 4000 microfarad with reasonable accuracy. Introduction We measure value of the capacitors when the values written on the capacitor’s body is not legible, or to find the value […]

How to Build Maxwell Inductance-Capacitance Bridge for measuring High Value Inductors
For measuring high inductance like 100H, the bridge we use is: James Clerk Maxwell Bridge which people also call Maxwell Inductance-Capacitance Bridge. It is made for medium to high Q inductors but when the inductance is large then it still behaves nicely, so people mostly prefer this one. Audio/Video Representation Basic Concept Basic idea of […]
6 Simple Capacitance Meter Circuits Explained – Using IC 555 and IC 74121
In this post I will talk about 6 easy yet accurate capacitance meter circuits using the ubiquitous IC 555 and many other easily available ICs. How Capacitors Work Capacitors are one of the main electronic components which come under the passive component family. These are extensively used in electronic circuits and virtually no circuit can […]
3-Digit LED Capacitance Meter Circuit
This project is yet another test equipment that can be extremely handy to any electronic hobbyist, and building this unit can be a lot of fun. A capacitance meter is a very useful test equipment as it allows the user to check a desired capacitor and confirm its relaibility. Ordinary or standard digital meters mostly […]
