The clap switch circuits explained here will toggle a connected load ON and OFF in response to alternate clap sounds? Here I have explained 4 unique and simple designs which can be selected as per user preference. The article talks about what the title suggests – a clap switch. A small electronic circuit when built […]

AC Motor Speed Controller Circuits using Back EMF
In this post I have explained a few circuit diagrams for building AC motor speed controller circuits using back EMF concept. Working Principle of AC Motors So now, all those home type appliances like electric drill machines, sander machines, sewing machines, food mixer machines, etc. they all are mostly using that AC motor which is […]
5 Interesting Flip Flop Circuits – Load ON/OFF with Push-Button
Five simple yet effective electronic toggle flip flop switch circuits can be built around the IC 4017, IC 4093, and IC 4013. We will see how these can be implemented for switching a relay alternately ON OFF by alternately pressing a single push-button or through touch pads, which in turn will switch an electronic load […]
3 Laser Beam Controlled Circuits Explored
A compact, battery-powered transmitter emits a LASER beam when the control push button is activated. The beam is frequency-coded to provide a maximum level of reliability in transmission. The receiver can be located at a considerable distance from the transmitter (up to several tens of meters). The light beam, by definition, remains highly focused, and […]
3 Frequency to Voltage Converter Circuits Explained
As the name suggests frequency to voltage converters are devices that convert a varying frequency input into a correspondingly varying output voltage levels. Here we study three easy yet advanced designs using IC 4151, IC VFC32 and IC LM2907. 1) Using IC 4151 This frequency voltage converter circuit using IC 4151 is characterized by its […]
3 Easy Capacitive Proximity Sensor Circuits Explored
In this post I will comprehensively discuss a 3 basic proximity sensor circuits with many application circuits and detailed features of the circuit. The first two capacitive proximity sensor circuits uses a simple IC 741 and IC 555 based concepts, while the last one is a bit more accurate and incorporates a precision IC PCF8883 […]
