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.
The tower 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 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.
Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
