A typical WLED wiring schematic with the components mentioned earlier would involve the following connections:
The ESP32 microcontroller would be placed in a header socket on the electrocookie breadboard, with a 1000uF capacitor wired in parallel to the power supply lines on the breadboard to smooth out any voltage fluctuations.
The LED strip would be connected to the breadboard, with the GPIO2 pin of the ESP32 connected to the data line of the LED strip.
A barrel jack would be used to provide power to the entire circuit, with the positive and negative terminals connected to the power supply rails on the breadboard.
An optional MAX4466 amplifier could be added to the circuit to make it sound-reactive. This would involve wiring the MAX4466 amplifier to the GPIO34 pin of the ESP32, which is capable of reading analog signals using the onboard DAC.
With the addition of the MAX4466 amplifier, the LED strip could be controlled and customized based on sound levels, creating a dynamic and immersive lighting experience that responds to music or other audio input. While WLED provides an excellent platform for sound-reactive LED projects, there are also other options available. LedFX, for example, is a software-based solution that allows users to create sound-reactive lighting effects using their computer and Wi-Fi-enabled LED controller.
To use LedFX for sound-reactive LED projects, users would need a Wi-Fi-enabled LED controller such as the ESP8266 or ESP32, as well as the LedFX software installed on their computer. Once configured, the LedFX software can be used to create a wide variety of lighting effects that respond to sound, ranging from simple color changes to complex animations and patterns. While LedFX may require a bit more setup than WLED, it provides a powerful and flexible platform for creating sound-reactive LED projects that can be controlled and customized from a computer.
The accompanying wiki page would include a Bill of Materials (BOM), 3D model files, and schematics to help viewers build their own custom lighting systems, as well as additional information and troubleshooting tips to assist in the process. It would also provide resources and information for using LedFX with ESP8266 or ESP32-based LED controllers, enabling users to explore the creative potential of sound-reactive LED projects in new and exciting ways.
