[Marklar] needed an IR receiver for a project he was working on, and his local electronics store was fresh out. He dug through his junk pile and found an old stereo receiver, so he decided to pull the IR module from it before tossing it out. Once he had it taken apart, he figured that he could utilize the wide array of electronic components he found inside, and set off to start a new project.
The control panel housed the components which interested him most of all. Using an Arduino, he was able to easily interface with the rotary encoders as well as the buttons, giving him a cheap and easy way to control his home lighting system. With a bit of programming, he was able to map lighting presets to various buttons, as well as use the rotary encoder to control the LEDs’ brightness and color. As an added bonus, he kept the IR receiver intact and can control his setup wirelessly as well.
Check out the video we have embedded below to see his scavenged control system at work.
