Random Raindrop effect

Hi

I have 22 led strips (APA102C / 1 meter each / 30 led per meter)
Hanging with equal gap
I would like to make a raindrop effect in each strip with random number of pixels (no fading or trail effect required)
Please some one advise which Arduino board I can use to control 22 x 30 pixels
Also is there any example code for random raindrop effect available to start with?

Thanks

The usual boards like Uno or Nano have to little RAM für 22x30 pixel. Maybe a Mega could do it, but I’d go with a Teensy or an ESP8266 (even without WiFi!).

Some inspiration for your effect: https://www.youtube.com/watch?v=7VH_mzjnUwE

Good luck and have fun! :slight_smile:

Good job. Rain drop video is realistic.
I Will update soon.
By the way I saw your water drop with lightning video.
Could you please share the link as well.

Actually, it’s (almost) the same code as the thunderstorm. Just stripped down to two columns instead of eight. :slight_smile:
