I have compiled a complete list of categories on this website to help you quickly find and navigate the electronic circuits you’re looking for. Let’s get started. Arduino Projects for Engineers In this category I have introduced comprehensive Arduino circuit designs for EEE and BE students. These include detailed explanations, images, and online support, which […]

Convert any H-Bridge Inverter to Sine Wave H-bridge Inverter
In this post we’ll discuss how to convert any ordinary square wave H-bridge inverter into an almost pure sine wave inverter circuit. Basic Concept The idea is simple, just chop the low side MOSFET gates of the H-Bridge with reverse SPWM (Sinusoidal Pulse Width Modulation) waveform. This will force the low side 50 Hz, or […]
Automatic Door Controller Circuit Diagram using a Single Push-Button
This door controller circuit works in this way: Initially the door is in the closed state. When a push button is pressed, the door begins opening until it reaches the end of the course. When it reaches the end, it automatically reverses its direction and now the door begins closing. It keeps moving until it […]
Day/Night Triggered Automatic Door Lock Circuit
In this post I have explained a simple day, night triggered automatic door lock circuit, which can be used for autonomously unlocking a kennel door during day break, and locking it when night sets in. The idea was requested by an avid reader of this blog, Mr. Norman, as given below. Design Request and Specifications […]
Simple Ceiling Fan Regulator Circuit
A simple electronic ceiling fan regulator circuit using a triac and a diac is a common type of circuit which is used to control the speed of a ceiling fan. This circuit basically works using phase control principle, in which the voltage supplied to the fan motor is varied by controlling the firing angle of […]
12 Amp Power Supply Circuit using Parallel LM317 ICs
This adjustable power supply is capable of delivering a maximum output of 12 A with an adjustable voltage from 4 V to 20 V through many LM317 ICs connected in parallel. It will allow testing of any device requiring a significant power supply, such as a direct current motor, a car amplifier, or even a […]
