@groundFungus You are right. I'd really like to use 5mm and 3mm LEDs though because of the amazing compatibility they have with Lego bricks...
@Wawa Those look really interesting! Seems like a very simple setup also.
How many of these addressable LEDs could you chain to a single pin? I didn't see any information about that. I guess I could calculate it based on how long each update takes?
Also, would you be able to turn some of the LEDs in a single chain off while keeping others on?
Thanks! Really appreciate the valuable information!
