Remote Controlled ATS Circuit – Wireless Grid/Generator Changeover
In this post I have explained a remote controlled automatic transfer switch for enabling an automatic grid to generator changeover action from a specified distance. The idea was requested by Mr. odudu johnson. Technical Specifications Project description: Automatic changeover switch with wireless generator control abilities or mechanism. The generator rating is going to be between […]
Remote Controlled Trolley Circuit without Microcontroller
In this post I have explained how to make a cheap yet powerful remote controlled trolley which can be maneuvered left, right, forward and reverse as required, by the user using the given remote handset. The idea does not rely on an microcontroller circuit. In one of my previous posts I discussed about a simple […]
How to Make Ultrasonic Remote Control Circuit
This ultrasonic remote control circuit can be used to switch and control any appliance ON/OFF through a relay in the receiver circuit. Written by: S.S. Kopparthy Using Ultrasonic Waves This circuit is a different one that uses ultrasonic sound waves whose frequency ranges from 40 KHz to 50 KHz. These waves can’t be heard by […]
Remote Controlled Ceiling Fan Regulator Circuit
In this article I have explained a simple infrared controlled fan regulator or dimmer circuit using ordinary parts such as a 4017 IC and a 555 IC. Circuit Operation Referring to the shown remote controlled fan dimmer circuit, three main stages may be seen incorporated: the infrared signal sensor stage using the IC TSOP1738, the […]
