We will discuss 4 concepts here, which are as follows: 1) Automatic Staircase Lamp Circuit using PIR The first automatic staircase light circuit describes a simple […]
2 Mosquito Swatter Bat Circuit Diagrams Explained
Mosquitoes are a big menace to humankind and these are present in every corner of the world. A cool way of avenging yourself could by eliminating these “devils” through electrocution. A mosquito swatter bat is designed just for this. I have explained how to build its electronic circuitry. The idea was requested by Mr. kathiravan d. […]
2 Digital Potentiometer Circuits Explained
In this post I have explained a 2 simple, single chip digital potentiometer circuits which can be controlled through a single pushbutton, a dual pushbutton (up/down) or even through external digital (CMOS/TTL) input triggers. 1) About DS1869 Dallastat TM is a rheostat or potentiometer. This unit delivers 64 conceivable consistent tap outputs over the over-all […]
Inductors in AC/DC Circuits Explained
In this post I have explained the response of inductors to DC and AC voltages as well as when applied with capacitors which is often used as a complementing part with an inductor. Properties of Inductor Inductors are known for their property of storing electrical energy in them in the form of magnetic energy. This […]
How to Protect MOSFETs – Basics Explained
In this post I will comprehensively explain how to protect mosfets and prevent mosfet burning in electronic circuits by following some basic guidelines related to correct PCB layout, and careful manual handling of these sensitive devices. Introduction Even after connecting everything correctly you find the mosfets in your circuit becoming HOT and blowing off within […]
