Vadim Panov’s new project is about an IR controlled light switch that operates with any RC-5 compatible TV remote. His switch is built around the ATTiny2313 MCU clocked at 8MHz. The IR receiving part is designed for decoding the 36KHz modulated IR signal using the TSOP1736 device.
IR controlled light switch
The thing I came up with at the time was a light swich for my room controlled over an IR remote from TV. Remote that I had used RC-5 protocol, hence the firmware is suited for any RC-5 compatible remote.
Everyone is familiar to the everliving problem with switching the lights off in your room before going to bed and stumbling back across the room. The IR switch I describe here solves that problem, and I can definitely tell that this project was a success – I am still using it with no regret.
A couple years ago I posted a very simple IR remote control switch for an electrical appliance, that can be turned on and off through any TV remote. Here’s a more advanced one that offers four relay switch control through NEC IR protocol using PIC12F675 microcontroller.

This project describes a technique of adding the remote control feature to an electrical appliance. The goal is to construct a black box where you can plug-in your 120V AC appliance (it can be easily modified for 220 V mains supply too) and control the ON and OFF operations with a TV or DVD remote that uses modulated infra-red (IR) pulse train of 38 KHz frequency. I did this project for my wife who studies late at night on her bed and later feels tired to stand up and turns the light off. Now she does it from bed with the TV remote. The good thing about this project is that it does not use any microcontroller and is only based on the CD4017 decade counter IC.
