Unlike our "12V" style tower lights , no wiring or microcontroller programming is required. It's completely plug-and-play for use with any computer that has a USB port, even a Raspberry Pi SBC - so we recommend it when you just want to get something running and don't want to noodle around with 12V power plugs and transistors .
The buzzer light is powered and controlled over USB, so just plug it right in. Inside is a microcontroller connected over a CH43x USB-to-UART chip, so you'll need to install a CH43x driver for the COM/Serial port to show up .
Once the serial port is created, connect to it over 9600 baud and send command codes to turn on and off the LEDs and enable/disable the buzzer. There's also a blink command, so you don't have to continuously turn on/off the LED to have a pulsing/blinking effect. See below for an example Python script that will toggle everything on/off to test.
