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 Useful Temperature Alarm Circuits Explained
In this post I have explained the working of 3 interesting and useful temperature alarm circuits through detailed circuit diagrams. A temperature alarm circuit is basically a device which is designed to detect a temperature threshold and sound an alarm as soon the temperature exceeds over, or drops below the desired temperature detection threshold. 1) […]
4 Automatic Day Night Switch Circuits Explained
The 4 simple light activated day night switch circuits explained here can all be used for controlling a load, normally a 220V lamp, in response to the varying levels of the surrounding ambient light. The circuit can be used as a commercial automatic street light control system, as a domestic porch light or corridor light […]
IC 7805, 7812, 7824 Pinout Connection Explained
In this post I have explained how to connect common 78XX voltage regulator ICs such as 7805, 7812, 7824 etc for getting fixed regulated output voltages at 5 V, 12 V, or 24 V outputs respectively. The input voltage must be at least 3 V higher than the desired output voltage. For example, if a […]
Simple Colpitts Oscillator Circuits Explained
In this post I have explained how LC oscillator circuits functions and we will be constructing one of the popular LC based oscillator – Colpitts oscillator. What are Oscillators Electronic oscillators are used in most of our daily used electronic gadgets ranging from digital clock to high end core i7 processor. Oscillators are heart of […]
CMOS Astable, Bistable, Monostable Circuits Explained
In this article I have explained how to use the low-cost CD4001 and CD4011 quad 2-input gate CMOS integrated circuits in bistable, astable, and monostable multivibrator applications through forty different manners. We also learn how to enhance and modify these configurations to produce highly improved outputs from these multivibrators. When CMOS logic gates are configured […]
