2 Simple Infrared (IR) Remote Control Circuits
The proposed infrared or IR remote control circuit can be used to operate an appliance ON/OFF through any standard TV remote control handset. In this write up I have explained a couple of these simple infrared remote control circuits designed for controlling any given electrical appliance through an ordinary or TV remote control unit. Introduction […]
2 Simple Induction Heater Circuits – Hot Plate Cookers
In this post I have explained 2 easy to build induction heater circuits which work with high frequency magnetic induction principles for generating substantial magnitude of heat over a small specified radius. The discussed induction cooker circuits are truly simple and uses just a few active and passive ordinary components for the required actions. Update: You […]
2 Simple Bidirectional Motor Controller Circuits Explored
A circuit which allows a connected motor to operate in clockwise and anticlockwise directions through alternate input triggers is called a bidirectional controller circuit. The first design below discusses a Full bridge or H bridge based Bidirectional motor controller circuit using the 4 opamps from the IC LM324. In the second article I have explained […]
2 Simple Arduino Temperature Meter Circuits Explored
In this article, I will show how to construct a couple of easy Arduino temperature meter circuits which can be also used as a LED room thermometer circuit. The circuit is designed to display the readings in doted/bar LEDs. This project can be implemented for applications where ambient temperature plays a crucial role or it […]
