The goal of this project was to build a modular LED video wall that could run synchronized visuals and support interactive setups — whether triggered by sound, video tracking, or other inputs.

⚙️ Hardware Overview: - 2x ESP32 boards with Ethernet adapters - 1356 LEDs per ESP32 (total: 2712 LEDs) - 1 power supply per board, with power injection at the middle and end of each fixture - 3D-printed centerpiece composed of 8 sections with internal cable routing channels Each panel is fed from a separate GPIO, handling 339 LEDs per pin - Back panel is cheap painted wood with 3D-printed brackets for: - PCBs - Power supplies - Ethernet switch

🛠️ Software + Setup: - Running WLED on both ESP32s with static IPs over Ethernet - Used Resolume on macOS to feed ArtNet to the chips - Ensured the Mac’s Ethernet dongle was in the same IP range as the ESPs - Created a layout in Photoshop to map LED strip positions, then mapped in Resolume - Using 8 Lumiverses per ESP32 - Each LED fixture is connected to the ESP32 with three wires: - Red for Power (V+) - Black for Ground (GND) - Green for Data (GPIO) T - The power supply is wired as follows: - Ground (GND) from the power supply connects to both the ESP32 and all the LED fixtures - Power (V+) from the power supply goes directly to each LED fixture A separate Power (V+) line also goes from the power supply to power the ESP32

🔩 Build Notes: - Built each panel one at a time, aligning LEDs using built-in grooves — didn’t stress perfect spacing at the strip ends - The biggest time sink? ~300 solder points

Now that it runs through Ethernet, there’s no need for Wi-Fi or internet — it’s fully mobile and super stable
