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 […]
433 MHz RF 8 Appliances Remote Control Circuit
In this post I have explained a circuit which can be used for controlling 1 to 8 appliances with a single RF 433MHz remote control handset. Now you can control fans, lights ACs, oven etc within a range of 50 meters with the same remote. In a few of my earlier posts I have comprehensively […]
Remote Controlled Submersible Pump Circuit
In this article I have explained a simple remote controlled submersible pump circuit which could be simply configured using any standard 2 channel 433MHz remote control modules. The idea was requested by Mr. James Smith Circuit Objectives and Requirements I have read a lot of your post and have successfully implemented them several times. Now […]
RC Helicopter Remote Control Circuit
In this post I have explained a simple RC helicopter remote control circuit using 433kHz RF modules, without any microcontroller or complex joystick implementations. The idea was requested by Mr. Jitendra. Circuit Objectives and Requirements I am making a large scale RC helicopter. In which I am using 4 motors. For 1st main 12v motor: […]
Ultrasonic Smart Automatic ON/OFF Switch Circuit
In this article we are going to build a smart automatic ON/OFF switch using Arduino, which can turn on or off gadgets automatically by sensing the presence of human nearby through the concept of ultrasonic. We are going to use ultrasonic module and Arduino to sense the presence of human which activates the gadgets such […]
