I’m working on an interactive music installation for a local event, and I’ve started working on using WLED to control LED effects.
I’m using LEDFX to drive WLED with music synchronized effects on an LED strip. I have an analog input that participants can adjust (think distance sensor / knob / etc) which I would like to basically change the effective “length” of the strip, so that the incoming E131/Artnet data is only output to some % of the LEDs attached, and the rest remain dark.
Essentially I want something like the “Percent” effect, but with active LEDs set to the E131/Artnet input instead of an internally generated effect, if that makes sense. Any idea how to do this from a usermod? Would like to have a standalone usermod and avoid modifying e131.c if possible.
Side note, I do have a custom WLED build working with a usermod I wrote that reads in an analog voltage and sets the intensity of the Percent effect, which works great.
Thanks!
