## Description 

THE REACTOR'S MELTING DOWN! GRAB THE FUEL CORE, JENNA, AND EVACUATE THE COMMAND CENTER! With this **Rotating LED Warning Light with Adjustable Volume Buzzer Alarm,** you can monitor and easily alert humanoids as to the status of a project, machine, or even if the bathroom is occupied!

This alarm is very very simple - provide anywhere from 3V to 12V DC to the two power wires, and the LEDs inside start lighting up in a rotating manner. If the volume knob is turned up, you'll also get an incredibly-annoying buzzer sound as well.

If you want to turn this on only sometimes, you'll want to use a [power transistor (like the venerable TIP120)](https://core-electronics.com.au/tip120-power-darlington-transistors-3-pack.html) or [power FET (like this nice N-Channel MOSFET)](https://core-electronics.com.au/n-channel-power-mosfet-30v-60a.html) to enable or disable power. Since it isn't inductive, you don't need a protection diode. [Adafruit have an example guide on using transistors to power a high current item here](https://learn.adafruit.com/transistors-101/example-uses).

If you want something with multiple colors, Adafruit got some really nice [tower lights here](https://core-electronics.com.au/search/?q=tower+light).
