5.2. Initial WLED Configuration
After initial power-up or a reset, the controller will create a Wi-Fi access point. Connect to this network using a smartphone or computer and navigate to the WLED web interface (usually 192.168.4.1) to configure your Wi-Fi network and LED strip settings.
5.3. Microphone Configuration
For the microphone function to work correctly, specific parameters need to be configured in the WLED interface, especially after a reset. This setting applies to firmware version 0.14 and later.
- Microphone type: Generic I2S
- I2S SD pin: 26
- I2S WS pin: 5
- I2S SCK pin: 21

6.3. App and Web Interface Control
Control and configure your LED strips using the WLED application available for smartphones or by accessing the controller's web interface through any standard browser connected to the same Wi-Fi network.
7. Maintenance
- Keep the controller clean and free from dust. Use a dry, soft cloth for cleaning.
- Do not use harsh chemicals or abrasive cleaners.
- Regularly check wiring connections to ensure they are secure.
- Ensure adequate ventilation around the controller to prevent overheating.
- Periodically check for WLED firmware updates to benefit from new features and improvements.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LEDs do not light up. | Incorrect wiring, no power, faulty LED strip, incorrect WLED settings. | Check power supply and connections. Verify LED strip functionality. Review WLED settings for correct LED type and pin assignment. |
| Controller not connecting to Wi-Fi. | Incorrect Wi-Fi credentials, out of range, network issues. | Ensure correct Wi-Fi SSID and password. Move controller closer to router. Try resetting the controller and reconfiguring Wi-Fi. |
| Microphone function not working. | Incorrect microphone configuration in WLED. | Refer to Section 5.3 for correct microphone settings (I2S SD pin, WS pin, SCK pin). Restart the device after configuration. |
| LEDs display incorrect colors or erratic behavior. | Incorrect LED type selected in WLED, data line interference, power issues. | Verify the LED strip IC type in WLED settings. Ensure proper grounding and sufficient power supply. |
