Here we are talking about controlling things like lamps, motors, heaters, and other similar electrical loads. The devices we use for this purpose are called thyristor and triac, OK? Both these devices, thyristor and triac, they can actually do this job like simple switch ON/OFF or they can also adjust the power given to these […]
Control
Remote Control Circuit Using FM Radio
In this post I have explained how to build a simple FM remote control circuit for toggling small AC loads such as lamps, fans etc using an ordinary FM transmitter circuit and a modified FM radio circuit. This remote control system enables the user to get an ON/OFF control on any desired appliance, by simply […]
2.4 GHz 10 Channel Remote Control Switch Circuit
In this post I will show how to construct a 10 channel remote control switch circuit based on ISM (industrial, Scientific and Medical) band. Introduction The ISM band is operated at 2.4 GHz, which can be used without licensing with reasonable power output. The proposed project is general purpose ON/OFF wireless switch, which can be […]
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 […]
Arduino IR Remote Control Circuit
In this post I will show how to construct a customizable Arduino based IR (infrared) based wireless remote control switch, which consists of IR remote and a receiver, you may modify according to your needs. In the later part of the article I have explained about an upgraded foolproof version of an IR remote control […]
Make this IR Remote Control Range Extender Circuit
In this post I have explained how to increase or extend the range of an ordinary infra red or IR remote control through a 433MHz RF remote control system. IR Range Extender Concept The idea of this circuit is to feed the IR data from an IR transmitter into the transmitter input of an RF […]
