We want to install a music-sensitive light system using four or five LED-strips.
We have several ideas but no experience with this topic.
Following plan: You connect your phone with the Raspberry using Bluetooth or WiFi and Spotify Connect (raspotify). A program controls the LEDs based on the music input (probably a rewritten version of https://github.com/scottlawsonbc/audio-reactive-led-strip). The audio is then redirected to our stereo system.
I would also program some basic features (single Color, fade, ...) and we wanted to use WS2812B strips with 3 or 5 Meters and 30 or 60 LEDs/m.
Now I have some problems/questions:
- Apparently it’s not possible to control music and LEDs at the same time. Could an extern sound card fix this?
- Is it possible to control so many LEDs with a Raspberry Pi?
- Some say that you need a level shifter to connect the Raspberry Pi with the LED strip. Is it really necessary?
- I read that audio input via Bluetooth is quite bad especially when WiFi is switched on. WiFi would be necessary to control the program (otherwise we need a small touchscreen or something like that). Can an extra Bluetooth dongle solve this issue?
As we are all new to this, we appreciate every answer or helpful comment or idea!
