ANDONT 7-Color USB LED Tower Signal Light with Buzzer, 5V DC, ABS Body, PC Lens, Plug-and-Play

Nice quality, compact size, convenient lighting:This product is well made and feels durable and solidly constructed while handling. The light is relatively compact, making it easy to move around or store away when not in use, but the LED lighting gets bright enough where you can see it pretty well even from a distance. This product is very convenient since it can be operated via USB and doesn't rely on an outlet to power up. The device is also pretty simple to control and adjust the lighting, making it a good option for a number of different use cases.Overall, this is a good product and I would recommend.

The light works well. There is one issue with the instructions on the product page.Just know that the buzzer "off" is 0x01 and on is 0x02 - you'll be surprised if you send the command expecting it to be off with their instructions.I don't use their software, never trust stuff like that. I use Python and write small interfaces using their serial module.This popped-up on my windows PC as COM7 (yours may vary). A simple bit of code makes it work.Pretty bright and an annoying buzzer - exactly what the doctor ordered.And just for completeness, if you missed it in the product page, it's 9600 baud, 1 stop bit with no parity.

This is an interesting device, driven via Hex data via the USB port.I used the URT Assistant SW from the MS Store. You send a Hex string and it activates the light, color, buzzer and/or blink rate. You connect at 9600 baud, 8-bit, 1 stop bit and type in the hex string.Example: To light the fixture send: FF 02 01 02 AA - Which tells it to: Open comms, Light Green, no buzz, 0.85 second Flash rate, Close comms.It works as expected.Other reviews and the product description are very helpful to get this running. It WILL NOT work without something (software) to send the Hex data to the fixture. This would be great for use with an Arduino, Raspberry Pi or other micro controller.I'm going to setup a simple program on my PC to light the lamps for use for a raffle drawing - Let folks know when a drawing is coming, waiting for a prize claim and prize winner is about to expire.Brightness is OK. Not daylight sufficient, however.The Buzzer (beeper) is about 80-90dB, so not too loud.Teh mount is well made for mounting on a flat surface. No hardware included.The clear cover is removable with a twist, but is probably NOT water resistant. The base is removable by pulling the fixture off of the aluminum mounting shaft. Teh USB cable threads through this.The Buzzer sound is vented out of the bottom of the fixture.Teh USB cable is not very long - about 30".

This industrial signal has seven colors to communicate. It integrates with existing systems withhout needing a PLC. It's a compact design so doesn't take up much room. It can be controlled by a PC with user-friendly software. It doesn't take technical expertise to set this up.
