What is WLED?
WLED is a powerful yet easy-to-use solution for controlling LED strips, offering advanced features, smart home integration, and stunning lighting effects without complex coding. It’s an ideal choice for both beginners and professionals looking to create customizable and dynamic lighting projects.
Here we will use the WLED web installer to upload the firmware. First, connect the ESP32 or ESP8266 to the laptop.
You just need a browser like Google Chrome or Microsoft Edge.
Open a browser and go to WLED Web Installer – https://install.wled.me
How to install the WLED firmware
In the following steps, I have explained how to upload firmware to ESP32 for WLED projects using the WLED web installer.
Select the Firmware in WLED web installer
In WLED Web Installer first, select the Firmware version in the WLED web installer.
Then select the board (ESP32 or ESP8266).
Click on “Install“.

About the WLED platform
WLED is a popular open-source firmware for controlling addressable LED strips using microcontrollers such as the ESP8266 and ESP32. It provides an easy and powerful way to create stunning lighting effects without the need for complex programming.
Once installed, WLED allows users to control LEDs through a web interface, mobile app, or even voice assistants, making it highly versatile for both beginners and advanced users.
One of the biggest advantages of WLED is its rich set of built-in effects and color presets. Users can choose from hundreds of dynamic animations, customize brightness, speed, and colors in real time, and even sync lights to music with additional hardware. It also supports segments, allowing different parts of a single LED strip to display different effects simultaneously, which adds a professional touch to any lighting setup.
WLED also integrates seamlessly with smart home ecosystems. It supports protocols like MQTT, HTTP, and can be connected to platforms such as Home Assistant, Alexa, and Google Assistant. This makes it ideal for creating fully automated lighting systems that respond to schedules, sensors, or user commands.
Another key feature of WLED is its user-friendly setup and flexibility. It works with a wide range of LED types like WS2812B, SK6812, and more. Whether you’re building ambient lighting for your room, decorative lighting for festivals, or advanced IoT lighting projects, WLED offers a reliable, customizable, and cost-effective solution.
