Christmas is nearing and we start thinking of decorations and lighting projects. There are tons of choices what to use. But if you want something more, then try adding something your own like remote control for Christmas lights. By following an instructable you will be able to build an SMS controlled lights.

The idea was to use Arduino Yun, protoshield with small breadboard, a 5V relay, buzzer and few other small things. Relay is simply attached to light controller button circuit so it could take over with Arduino control signal. Arduino Yun is used to connect to internet of things website called Temboo. It allows setting up remote services where you can send messages and so pass parameters to Arduino and from it. Once set you can start sending SMS messages like “Lights on” or “Lights off” and this way switch or toggle light effects. Each control is followed by audible alarm from piezo buzzer. Of course you can extend this project by adding more light circuits or give more switching options as you like.
