Remote Control of the Living Room and Dining Room Lights and Fans

About: An avionics engineer by profession. I am a huge DIY freak and my proudest possessions are my tools. Since 2016, I have been interested in Arduino and using them to simplify / automate stuff that can be used ...

Although there a number of instructables on this site in this very subject, it is very exciting for me as it is my first project. Because of the layout of the rooms (see picture attached), I had to resort to more than IR to control the two separate Arduino boards. A 433 Mhz Tx / Rx provides thee required transmission between the two switch board.

It was interesting to see my first project turn out into something which I know will be used every day at home. Overall I am delighted at the results.

The Tx board comprised of :-

(a) Arduino Uno

(b) Kayees IR receiver

(c) 433 MHz RF Transmitter

(d) a set of four relays operated at 5 volts and

(e) some bare PCB, wires and soldering iron

The Rx board comprised of pretty much the same things except that the 433 MHz RF Transmitter was replaced by the 433 MHz RF Receiver.

    Not that I want to criticize but I am not really seeing an instructable here. Its more like "Hey, I managed to control lights and a fan in two rooms with two arduinos and I used a soldering Iron"
    No doubt it is an interesting project, but a lot of people might be helped by a more detailed description of what you did, how you connected stuff and possible the program you used

    Ooops ! I came across your comment only today after I posted my third POST (won't call it an instructable after you pointed out something valid) :)

    Yeah I guess from a beginners perspective, I agree it would help one loads if I threw in a wiring schedule as well. Point noted and will make that a part of my future instructables.
