• Connect the ESP32 to your Wi-Fi network by entering the credentials during the installation process.
• Open the WLED app on your smartphone and connect to the ESP32.
• In the app, set the signal pin to GPIO 17 (or your chosen pin) and specify the number of LEDs on your Christmas tree (e.g., 300).

To enable Alexa voice control for your RGB Christmas tree lights, begin by setting an invocation name and selecting the "emulate Alexa device" option in the WLED app. This allows seamless integration with the Amazon Alexa ecosystem, enhancing the interactivity of your festive lighting setup.
