With this Tri-Color USB Controlled Tower Light with Buzzer, you can easily monitor and alert humanoids as to the status of a project, machine, or even if the bathroom is occupied!
Unlike our other 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. It’s also got a great adjustable-angle body and three mounting holes on the base for easy installation.
Once the serial port is created, connect to it over 9600 baud and send command codes to turn on and off the red, yellow, and green 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.
