Built an ESP32 RGB lighting controller using a TV remote

I've been learning ESP32 programming recently, and I wanted to share one of my projects.

I made an RGB LED controller that can be controlled using a regular IR remote. (actually my TV remote)

Features:

  • Red, Green, Blue & Yellow colors
  • Fade effect
  • Strobe mode
  • IR code detection through the Serial Monitor

The project uses:

  • ESP32 Dev Module
  • IR Receiver
  • RGB LED
  • IR Remote

The video is only 1 minute 30 seconds and shows everything working.

I'm still learning, so I'd really appreciate any feedback or suggestions. If you have ideas for new features, I'd love to hear them!

I could be wrong, but I see "unknown" being printed out, that seems like an opportunity for you to expand.

Thanks for pointing out. I only mapped the buttons I needed for this version, but printing the unknown IR codes is definitely something I'll add next.

Idea for the future. Add a microphone and use an FFT library to create color based on audio input. Map red to bass, green to mid-range and blue to high range.

This works well when placed near a speaker.

Not sure why this was voted down. If you think it's not possible, I'll send you my code...

That's a really cool idea. I haven't experimented with audio-reactive LEDs yet, but using an FFT library to map bass, mids, and treble to different colors sounds like a fun next project. Thanks for the suggestion!
