Adafruit Tri-Color USB Controlled Hemisphere Alarm Light with Buzzer

This Tri-Color USB Controlled Hemisphere Alarm Light with Buzzer is a versatile alert system for projects, machines, or even restroom occupancy. It's plug-and-play, requiring no complex wiring or programming.

Easily powered via USB from any computer, including Raspberry Pi SBCs, this device integrates a microcontroller connected through a CH43x USB-to-UART chip. Installing a CH43x driver allows for seamless serial port access at 9600 baud, enabling command codes for LED and buzzer control.

The LED array can be toggled on or off or set to blink, providing customizable alert signals. An example Python script can be used for testing, making it a practical solution for quick setup without technical hassle.
