Step-by-step guides for every level — from complete beginners to experienced builders.
Whether you are completely new to LED lighting or an experienced installer tackling a complex multi-zone build, these guides cover every stage of the process with practical, tested advice.
The How To Plan Your WLED Build guide walks through controller selection (ESP32 vs ESP8266, dedicated WLED boards vs bare modules), power supply sizing, wire gauge selection, the data resistor and level shifter requirements, the WLED firmware flashing process, and the full WLED configuration flow.
The Beginner's Guide to WLED answers the most fundamental questions: What is WLED? What hardware do I need? How does addressable LED control actually work? It includes a step-by-step first-build checklist and a list of the most common mistakes beginners make.
The Troubleshooting Guide covers the 12 most common WLED installation problems, organised by symptom. Each problem includes the root cause, step-by-step fixes in priority order, and the relevant WLED configuration setting.
Building a WLED installation involves decisions across multiple disciplines: electronics (power supply sizing, wiring, fusing), firmware (flashing, configuration, smart home integration), and physical installation (mounting, waterproofing, diffusion). These guides cover each area with enough detail to get a complete beginner from unboxing to a finished, correctly specified installation, and enough technical depth to be useful for experienced builders troubleshooting edge cases.
The Beginner's Guide explains what WLED is, what four hardware components you need (controller, LED strip, power supply, and wire), how they connect together, and the most common mistakes that first-time builders make. It is written for someone who has never worked with microcontrollers or LED strips and covers the terminology and concepts needed to understand the rest of the site.
The Build Guide walks through a complete WLED installation in five structured steps: controller selection (ESP32 vs ESP8266, pre-built vs DIY, level shifters), power supply sizing (using the Power Calculator, PSU derating, fuse selection), wiring (gauge selection, injection points, data signal), firmware installation (WLED web installer, initial configuration, LED Preferences), and a pre-power-on safety checklist. It covers both simple single-strip installations and more complex multi-zone builds.
The Troubleshooting Guide uses a symptom-based structure — find your specific problem (flickering, wrong colours, Wi-Fi disconnection, OTA failure, Home Assistant integration issues) and follow the diagnostic steps for that symptom. It covers power issues, signal integrity problems, firmware configuration errors, and network problems in order of how common each cause is, reducing the time spent chasing the wrong diagnosis.
The History page documents the development of WLED from Christian Schwinne's first 2018 release through the ESP32 migration, the community growth period, the effects library expansion, and the current state of the project. Understanding the project's history helps explain some of WLED's design decisions and the ecosystem of compatible hardware that has grown around it.
