Description
The Sound Visualiser is an interactive project built with a Raspberry Pi Pico W, programmed in Rust. It uses a ST-7735 TFT screen controller and a sound sensor module to create a dynamic visual experience, where a ball reacts to sound frequencies in real time. The ball's movement, such as jumping or bouncing is directly tied to the audio input. Additionally, a led strip is representing visually the sound's intensity, with varying brightness.
Motivation
The motivation behind this project comes from a desire to combine technology and music in a fun, interactive way. The use of a Raspberry Pi Pico and a sound sensor module provides a hands-on way to explore embedded systems and audio processing, while offering a creative approach which can be expanded in future iterations.

Hardware
For this project, I used a Raspberry Pi Pico Wireless Plus with headers as the main microcontroller to control the various components. The breadboard serves as the central platform to prototype and organize the components. Jumper wires are used to establish the necessary electrical connections between the Pico and the other modules.
The RGB LED strip (WS2812, 8 LEDs) is connected to a GPIO pin on the Pico, allowing for dynamic lighting control through software. The sound sensor module is wired to an input pin on the Pico to detect sound levels, enabling interaction with the system based on ambient noise. Finally, the ST7735 TFT display is connected to the Pico via the SPI interface, providing a compact display for visual output and feedback. Resistors are strategically used in the circuit to ensure safe voltage levels and current regulation across components.
This hardware setup allows for real-time control and monitoring, with the LEDs responding to sound inputs and the display showing relevant information.
