Our project is a sound reactive LED matrix display. This project requires a microphone, an Arduino R3 board, a matrix LED, and a computer with a type B wire to install the code into the Arduino board. The project converts sound waves from the microphone into electrical signals onto the matrix LED. As the sound input changes, the display on the LED matrix output changes as it creates responsive visual effects that are synchronized with the audio. These signals are amplified and processed by the Arduino it analyzes the frequency in real time.
