Control Lights, Fan, using TV Remote [Full Circuit Diagram]

Last Updated on June 18, 2023 by Swagatam 15 Comments

infrared red remote control using TV remote

In today’s world, the idea of control is strongly connected to the ability to use remote devices. Home automation, known as domotics, allows us to switch ON/OFF various things such as televisions, hi-fi systems, blinds, curtains, garage gates, and even the brightness of lights using a small control unit. The signals for controlling these devices […]

Sound Activated Remote Control Circuit

Last Updated on June 8, 2023 by Swagatam Leave a Comment

double sound operated ON OFF remote switch

This sound activated remote control circuit can be used to operate any electrical load ON/OFF, through a double sound command. Thus, the circuit ensures that the load cannot be operated through any random single sound triggers, which makes the circuit very fool proof. Our device will require two shifted sound commands. However, the second sound […]

Remote Control using Mains Power Line Communication

Last Updated on May 12, 2023 by Swagatam 44 Comments

main communication reciever

The proposed circuit will allow you to remotely control a mains AC operated appliance across rooms of your home through mains power line communication or PLC concept. In PLC technology, an electronic circuit which works as a transmitter is plugged-in to the mains wiring (220 V or 120 V) injects a modulating high frequency data […]

Remote Control Infrared Tester Circuit

Last Updated on January 2, 2024 by Swagatam 30 Comments

remote etster circuit

We all use remote control handsets for controlling various household devices such as TV, AC, Music systems, curtains etc, and sometimes we seem to have problems with these devices, or even a newly purchased remote controller unit occasionally seem to malfunction, and identifying the issue becomes quite difficult for us. This simple 2 transistor infrared […]
