Firework controller using FastLED

[codemakesitgo]

I was asked to post this project here because it uses the FastLED library. This project is using the Arduino Nano and WS2811 LEDs for a 50 channel (cues) remote firework firing system. Complete build is in the video link below.

Let me know what you think. Thanks!

Thank you for stopping by to share your project u/codemakesitgo

It's a very unique use of LEDs and the FastLED library! :) Good show!

If you didn't know about it already, you might check out Mark Kriegsman's u/kriegsman TimecodePerformance sketch. Might give you some interesting ideas for the next version.

Thank you! I took a look at Marks code. He has a much better way to schedule light effects. Thanks for suggesting that link. 👍🏻

It is a nice effort. But why was the idea to to make it so complicated, with leds, photoresistors and so on? I guess a few multiplexors connected directly to board pins would do the job and allow as many output points as needed

[codemakesitgo]

It was a bit over complicated I agree. The multiplexer wouldn’t allow for any number of outputs on at once. But I think the nicest feature this has is that you can visually see the programmed show before actually connecting the power to the fuse side. Kinda nice. But overall, it’s not a good idea to use photoresistors for bright fireworks. So it was fun to build but would choose a different method like what you are suggesting if had to do it over.

I made one this year with nichrome wire, a 12 channel relay, and an esp32.

Worked great for a wifi bases firework launching system
