However, commercial Art-Net hardware often comes with a steep price tag, costing hundreds of dollars. Today, we are introducing a project that allows you to build a stable, powerful Art-Net receiver using a simple **ESP32** and an Ethernet module for just a few dollars: **ESP32-Artnet-Node-receiver**.**[ESP32-Artnet-Node-receiver](https://github.com/mdethmers/ESP32-Artnet-Node-receiver)** ## **💡 Core Summary** ![Artnet ledstripcontroller: 2700+ leds, ethernet en wifi afbeelding 4](https://i.etsystatic.com/58985982/r/il/3cce3e/7011192787/il_794xN.7011192787_o7ag.jpg) This open-source solution utilizes an **ESP32 microcontroller** to receive **Art-Net (DMX over IP)** data from a PC or lighting console and convert it into control signals for addressable LED strips like **WS2812B or SK6812**. While it supports Wi-Fi, its standout feature is the support for **Ethernet modules (like the W5500)**, enabling seamless, low-latency wired data transmission. --- ## **🚀 Why is this project special?** ### **1. Unbeatable Cost-Performance Ratio** While commercial Art-Net to SPI (LED) controllers are expensive, this project requires only an **ESP32 board**, an **Ethernet module**, and some basic wiring. It integrates immediately with professional VJ and mapping software such as **MadMapper, Resolume, and TouchDesigner**. ### **2. Stability via Wired Ethernet** Many DIY ESP32 lighting projects rely solely on Wi-Fi. However, in environments with heavy interference or when controlling thousands of LEDs, Wi-Fi latency and packet loss can be fatal. This project supports PHY modules like the **W5500 or LAN8720**, guaranteeing fast and stable data processing via **Wired LAN (Ethernet)**. ### **3. High-Performance Multi-Universe Handling** Leveraging the ESP32's dual-core architecture, this node can handle massive amounts of data. It goes beyond a single Universe (512 channels), capable of receiving and processing multiple Universes simultaneously to smoothly control hundreds or thousands of LED pixels. --- ## **🛠️ How It Works** The system workflow is as follows: - **Source:** Lighting software on a PC (e.g., Madrix, Jinx!) broadcasts lighting pattern data via the Art-Net protocol. - **Network:** The data travels through an Ethernet cable (or Wi-Fi) via a router/switch to the ESP32. - **Receive & Convert (Node):** - The ESP32 listens for UDP packets on its assigned IP address. - When an Art-Net packet arrives, it parses the header and extracts the DMX data. - The extracted color data (RGB/RGBW) is immediately converted into the correct waveform for the LED strip (often using libraries like FastLED). > **Tech Tip:** For stable 5V LED control, it is highly recommended to use a **Logic Level Shifter (e.g., 74HCT245)** to boost the ESP32's 3.3V logic signal to 5V. --- ## **🎯 Use Cases** - **Media Facades & Interiors:** Mapping LEDs on building walls or indoor spaces to create music-reactive lighting. - **Stage & Events:** Installing custom pixel LED setups in DJ booths or stage props and syncing them with the main lighting console. - **DIY Smart Home:** Creating complex, high-speed lighting effects that off-the-shelf smart bulbs cannot achieve. ## **🏁 Conclusion** The **ESP32-Artnet-Node-receiver** project lowers the barrier to entry for hardware costs, allowing anyone to build a professional-grade lighting control system. If you want to fill your desk or studio with brilliant, synchronized light, it's time to pick up your soldering iron. --- Source: https://maker.wiznet.io/scott/projects/esp32-artnet-node-receiver/
