I have seen some 16x16 WS2812 pixel matrix on Aliexpress.com and coul not resist to buy it and make something with it.

So here is my creation, 16x16 WS2812 LED matrix panel. I have created some stand for that as well but i think it could be very nice on the wall as well:)

I have prepared some basic animation, but if you will make it and create your own animations please share it and let me know:)

If you want to use it with high brightness and lit lot of pixel please make sure that you have at least 8A, 5V PSU! For test and with low brightness you can use just USB cable.

Some basic idea mostly from here: https://www.brainy-bits.com/arduino-16x16-matrix-frame/

and from here: https://www.brainy-bits.com/create-arduino-array-from-pictures/

They are using arduino but you can use any MCU you want i think. I am using ESP32 here. I have added some light, temperature/humidity sensor and microphone for later use. Then you can display temp/humidity or control brigtness of LEDs according to ambient light or make some cool sound level meter etc.

If you want to change something in design, Fusion360 file is included.
