| + | The project uses the Adafruit_NeoPixel.h, LinkedList.h and Wifi.h libraries for controlling the LED strip and the webserver. | ||
| + | The main logic of the project is represented by the following steps: | ||
| + | * set up the Wi-Fi communoication, microphone pin, LED strip object and initialize a list containing the color of the LEDs | ||
| + | * in a loop: | ||
| + | * Unordered List Item* read the analogue value outputed by the microphone | ||
| + | * run the webserver, thus showing the client the webpage that controls the sound processing variants | ||
| + | * based on the current sound representation method, process the sound and add the current LED values | ||
| + | * go through each element in the LED strip's list and modify the colors of each one | ||

| + | The music visualization methods: | ||
| + | - simple visualization - based solely on the waveform | ||
| + | - average visualization - based on the average of sound intensities | ||
| + | - frequency based visualization - based on the frequency domain obtained with the FFT algorithm | ||

| ==== Conclusion ==== | ==== Conclusion ==== | ||
| + | This project represents an efficient, simple and nice solution for illuminating a room, visualzing music or any other sounds or just creating a desired mood. For me, it was a very good way to learn more about the ESP32 microcontroller and sound processing. | ||
| + | In my opinion, this project offers a great oppurtunity to be developed into a product that can be ultimately sold to awaiting customers that need something more customizable that the current market offers. | ||
