Pixel Matrix WS2812

thingiverse

I couldn't resist buying a 16x16 WS2812 pixel matrix from Aliexpress.com and creating something with it. Here's my creation, a 16x16 WS2812 LED matrix panel. I built a stand for it, but it would also look great on the wall. I've prepared some basic animations, but if you create your own and share them, let me know. To use it at high brightness and light up lots of pixels, make sure you have an 8A, 5V PSU. For testing or low brightness, a USB cable will do.

They use Arduino, but you can use any MCU you want - I'm using ESP32. I've added a light sensor, temperature/humidity sensor, and microphone for later use. Then you can display the temp/humidity or control the brightness of LEDs according to ambient light or make some cool sound level meter, etc. If you want to change something in design, there's a Fusion360 file included. I printed it on my Prusa i3 MK3 at 0.2 layers with 20% infill and mostly without support (only for inner holders) using PLA.
