![]() ![]() ![]() ![]() I don’t think I’m a good programmer, I think I’m a stubborn perfectionist. In my experience, once you start combining and making modifications to the examples it doesn’t take very long before you hit a wall. The examples that come with the Arduino software and the examples included with libraries are an excellent start to a project. Designing the software to operate on the Arduino Uno became the challenge. I could read the codes coming out of the remote-control, record them, and then program the Arduino to control the corresponding outlets. Another search on the web for an “Arduino library” and in this case, transmitter and receiver or tx/rx pair. The greatest advantage to using the Arduino family of microcontrollers for these types of projects, is that you can find open-source software to get started. In this case, I found the 315Mhz and 433Mhz transmitter and receiver pairs that are within the frequency range of most consumer wirelessly controlled outlets. Unfortunately, the results of this test wasn’t much better than the relay attempt.Ī search on the web for nearly any sensor or electronic doo-dad with “Arduino” will result in a number of products being sold for a few bucks. Eventually, I was able to convince myself that the best way to find out is to just try and see what happens. Hacking the remote control to send the signal for the ON or OFF button selected by a corresponding pin on the Arduino Uno shouldn’t be too difficult, right? The nagging concern that was preventing me from testing this idea was the fear that the signal would not be reliable and the Uno might “think” it had turned on a device when it actually failed. A home automation idea that I had bouncing around in my head for a while was to use wirelessly controlled AC outlets that use a hand-held remote-control. ![]()
