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 […]

Simple ESR Meter Circuits Explained
In this post I have explained a few simple ESR meter circuits which can be used for identifying bad capacitors in an electronic circuit without removing them practically from the circuit board. The idea was requested by Manual Sofian… Technical Specifications Do you have a schematic about ESR meter. Technicians recommend me to check the […]
10 Useful Function Generator Circuit Diagrams Explained
In this post I have explained how to build 10 simple yet useful function generator circuits using IC 4049, IC 8038, IC 741, IC 7400, transistors, UJTs etc. for generating accurate square waves, triangle waves, and sinewaves through easy switch operations. 1) Using IC 4049 Using only one low-cost CMOS IC 4049 and a handful […]
Arduino Frequency Meter Using 16×2 Display
In this article I will show how to construct a digital frequency meter using Arduino whose readings will be showcased on a 16×2 LCD display and will have a measuring range from 35 Hz to 1MHz. Introduction Being electronics enthusiast, we all would have come across a point where we need to measure frequency in […]
Making a Single Channel Oscilloscope using Arduino
In this interesting post, we are going to make a simple single channel oscilloscope using Arduino and a personal computer, where the waveforms will be showcased on the PC’s display and frequency and time period of the input waves will be displayed on the 16 x 2 display. Introduction Every electronics enthusiast once said “I […]
Digital Capacitance Meter Circuit Using Arduino
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 […]
