## Description

This is an I2C button module with RGB LED. The module not only supports reading button status like conventional ones, but also controlling RGB LED color and switching on/off the light independently, which could create more visual and interactive experiences for your projects. For example, when the system prompts users to press the button, the RGB light blinks in green; when the button is pressed, the light turns red.

This module has an onboard 3-bit DIP switch for setting 8 different I2C addresses, which means up to 8 such button modules can be cascaded together without occupying additional ports.
