My project is about creating a hardware controller using a Raspberry Pi Pico microcontroller and a rotary encoder to provide a convenient way of controlling various functions on a computer. The key features of this project include:

Volume Control: The rotary encoder can be used to adjust the system volume by simply rotating it clockwise or counterclockwise.

Application Switching: The controller allows you to quickly switch between different open applications on your computer by rotating the encoder. This can significantly improve productivity by reducing the need to constantly switch between applications using the mouse or keyboard shortcuts.

Desktop Switching: For operating systems that support virtual desktops (such as Windows and Linux), the controller can be used to navigate between different virtual desktops by rotating the encoder.

Media Control: A dedicated button on the controller can be used to play/pause media playback, providing a convenient way to control media without switching applications.

Microphone Mute: Another button on the controller allows you to quickly mute or unmute your microphone, which can be especially useful during video conferences or online meetings.

The project involves connecting the rotary encoder, buttons, and other components to the Raspberry Pi Pico's GPIO pins and running a Python script that translates the physical input from the encoder and buttons into corresponding actions on the computer. The script is written using the CircuitPython library, which simplifies the process of interacting with the Pico's hardware and sending keystroke and multimedia commands to the connected computer.

Overall, this project aims to provide a simple and intuitive hardware solution for enhancing productivity and streamlining common computer tasks, such as volume control, application switching, and desktop navigation.
