In this article I will explain a simple curtain controller circuit designed by me which can be used to control the opening and closing of a curtain through a remote control. Overview Referring to the circuit diagram in your screen, we can see there are just two relays employed for implementing a remote controlled opening […]

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 […]

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 […]

In this post I will show how to construct a few fireworks ignition circuits which can safely ignite them via IR remote and timer. We have proposed three firecracker igniter circuit designs using ordinary components which we will be exploring them in detail. Before we jump in to the circuit details, we have a word […]

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 […]
