Using Artnet DMX and the ESP32 to Drive Pixels
Englandsaurus 
Introduction
I like to make things glow probably far more than a colorblind person should, and I've been looking for new and interesting ways to control the output of different lighting applications without having to hard-code in different color sequences. I'd like to be able to have some sort of complex visual, and then have that be able to play on the lights without having to think about which LED needs to be which color in a display.
Required Materials
To follow along with this project tutorial, you will need the following materials:
Please note that although the WS2812 are 5V LED's, you can usually get away with driving small numbers on only 3.3V logic, so I'm going to skip the logic translation as this tutorial is mainly about DMX. You'll also need some 20AWG wire to connect the LED strip to your breadboard.
Tools
The following tools are required to follow along with this tutorial:
- Soldering Iron
- Solder
- Flux
- Breadboard
- Power supply
- Optional Fixed Voltage Power Supply (If you are going to create an actual LED installation, you'll need a dedicated power supply)
