In this article I have explained using circuit diagrams how a clipper and a compressor circuits work to processes an input audio signal as per the required output signal. What is an Audio Clipper An audio clipper circuit is basically used to alter or restrict the amplitude (volume) of an audio signal. There are mostly […]

10 Simple IC 555 Monostable Circuits Explored
In this post I have explained how IC 555 can be used for making 10 different types of monostable multivibrator circuits, such as one-shot type, debounce preventor, retriggerable type, touch switch monostable circuit and many more. A monotsable multivibrator circuit is a configuration in which, a short momentary pulse at the input of the circuit […]
7 Easy Sawtooth Waveform Generator Circuits using UJT, IC 555, and Transistors
In this post I have explained how to build 7 types of easy sawtooth generator circuits, using BJTs, UJTs, and IC 555. In a sawtooth waveform the voltage increases slowly in a slanting manner or diagonally, then as soon as it reaches the peak, the waveform voltage suddenly drops to zero. Once it drops to […]
9 Simple Solar Battery Charger Circuits
Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: In this post I will comprehensively explain nine best yet simple solar battery charger circuits using the IC LM338, transistors, MOSFET, buck converter, etc […]
7 Interesting IC 555 Siren and Alarm Circuits
In this post I have explained how to use IC 555 to create 7 interesting siren and alarm sound effect generator circuits. The versatile astable multivbrator configuration of IC 555 allows us to implement it for making various types of sirens and alarm circuits. This becomes possible because an astable is basically a waveform generator, […]
5 Simple Motion Detector Circuits using PIR
A PIR motion sensor alarm is a device which detects the infrared radiation from a moving human body and triggers an an audible alarm. In this post I have explained 5 simple motion detector circuits using op amp and transistor. We also discuss the pinout details of the standard passive infrared (PIR) sensor RE200B. We […]
