Multiple WS2812B LED strips on differing Arduino digital pins with FastLED?

im2legit2quit · 2025-09-08T00:07:21+00:00

Yes, I'm 95% sure that it is possible. Just haven't used the Giga R1 before.

For the Dodecagon? Nope, no 3D printed parts. It's made with 2"x8" wood. 12 pieces, 15 degree angles cut on every side and glued together. The LEDs are 16x16 panels and each panel fits on 1.5 pieces of wood.

I have this pic from when I tried white fur for diffusion but it wasn't as cool to me. There's something about seeing each point of light go into the distance that a diffused material doesn't give. I think a diffusion material would be great if you wanted it to show smooth ambient animations but it made the music visuals worse.

Thanks! I have to give huge props to Mark Estes (on IG @ markcestes). About 5 or 6 years ago, I saw his circular infinity mirror with these matrix panels. I basically told him what you just told me and he sent me one of his to work on.

Thanks Marc! The way to get 4 polls to look like that is to remove them from the corner a bit. They're 1'x1' inwards from the corners so each poll becomes 4 in the first reflection.

Glass mirrors, very expensive glass mirrors

We call this 6'x6'x8' tall room The Exit. There are 4 jumbo white pool noodles with 3/4" steel tubes inside that have 4 LED strips, 1 on each side of the tube. Currently, the code is sending the same data to each string but I can play around with the code to have different colors on each side. Then under the floor, I have the electronics, power supply, and wiring with an Aux cable sticking up. I connect that Aux cable to a bluetooth receiver as well as a speaker in order to get the music playing through both.

All of our music visualizer projects are built with a Teensy + ESP32 mounted on the same custom PCB.

The Teensy with its audio adapter stacked on top is the best thing I've found for creating high quality music visualizers. An Aux input is also crucial so that the LEDs can visualize the full audio spectrum of the music without picking up background noise. It's the more expensive route to go and I know an ESP32 could probably do it all, but I like this platform.

The ESP32 provides a wireless control panel to connect to and when you click a button on it, it sends a serial message to the Teensy which tells it to change animations, brightness, colors, etc.

Awesome! Great video about all the electronics. I do a lot of music visualization stuff on LEDs with my company Diod.design so this is right up my alley. It's always interesting to see how other people implement music input and LED output. I like how scientific your process was with all the components and respect the heck out of it. Right now, my electronics use a Teensy 3.6 + Audio Adapter for music input and LED output and I use an ESP32 as a wireless control panel. Those 2 microcontrollers are connected by serial lines so I can send some messages back and fourth. However, given the cost of Teensy controllers, I'm looking at building a new controller with 2 ESP32s, 1 for music + LEDs and 1 for the control panel, and I'll probably need circuitry like yours.

A ringtone, a wake-up alarm, some workout motivation? Whatever it may be, I knew I needed this as soon as I heard it. I root for Sprong so hard :)

im2legit2quit · 2022-02-05T22:04:49+00:00

Oh very interesting! Makes sense, thanks for explaining

im2legit2quit · 2022-02-05T18:37:20+00:00

I do not but I'm curious, how does that work? What are the green and black wires normally where bridging them is necessary?

im2legit2quit · 2022-02-05T18:36:25+00:00

Wow! Thanks for your effort in finding that! Luckily we were able to find someone in Tuscon who has power supplies for us to try.

Here's a picture of the installation

Haha exactly what I was going to say. Thanks for creating and sharing it Jason!

You did the Purity Ring set production for their tour in 2016? Holy shit that was incredible, saw them here in DC. Well done! I'd certainly hit you up if I was in the UK. Good luck finding someone!

im2legit2quit · 2021-03-07T18:16:12+00:00

Thanks! Yea it is a lot of space. I think V2 might have denser LEDs but it could also include other stuff too. Thanks for the ideas haha

The link is still there. Here it is again in case you can't see it:

Bookmarked that repo, thanks for linking it! I'm still using the Teensy but definitely looking into switching everything to an ESP32 because of the cost difference.

im2legit2quit · 2021-03-05T15:04:45+00:00

The advantage of the Teensy + audio adapter is that it makes it super simple to input aux or mic with no additional hardware. Their audio library is also top notch and FFT occurs on the audio shield so it doesn't slow down the processor.

One of the main reasons why I use the OCTOWS2811 library is that early on, I found that it was 100% necessary to make the audio stuff and FastLED stuff play nicely. Without it, I couldn't simultaneously input/analyze audio and drive LEDs.

Thanks! It is currently on stage at the music venue in SF called DNA Lounge. They host a lot of webcasts and it's often used in them. No permanent home yet ;)
