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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
