IR Remote Controllers protocol: 101 to advanced
Are you ready to unlock the secrets of infrared remote controls and take your DIY projects to the next level? In this video, I’ll show you how to use any infrared remote control to power your own creations! We’ll dive deep into the science behind these remotes and learn how they send signals. I’ll explain how the 4-byte code is sent, breaking down the binary system behind each button press.
You’ll discover how a 38 kHz carrier frequency helps differentiate your remote’s signal.
In this tutorial, we’ll test various remotes, build a simple circuit with an infrared receiver, and view signals on an oscilloscope. Then, I’ll demonstrate how to interpret and decode the waveform to make it work with a microcontroller, such as the STM32, in a 10-channel lighting system.
Plus, this video is part of a larger project series, so stick around to get all the files and schematics for building your very own system!
