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 […]

Wireless DC Motor Speed Control Circuit

Last Updated on August 30, 2021 by Swagatam 10 Comments

block diagram compressed

In this post I will show how to construct a wireless DC motor speed control circuit which can be controlled using any IR based remote controller. The proposed project has two main objectives; the first one is 5 step sequential speed control of a 12V DC motor using IC 555 (PWM) and controlling the PWM […]

Inverter Circuit with Feedback Control

Last Updated on May 14, 2021 by Swagatam 227 Comments

inverter circuit with feedback control compressed

In this article I have explained a couple of inverter circuits featuring an automatic feedback control for ensuring that the output does not exceed the normal specified AC output level, and also does not exceed the specified overload conditions. What is Feedback Control in Inverters A feedback control in inverter is generally incorporated to control […]
