What can we say, we like tower lights and other notification systems. But they’re often 12V and require a controller. These alerts are panel-mount friendly AND come with a USB cable for power and data. When plugged into a computer or Raspberry Pi they appear as a serial port. Send bytes over to turn on the red, yellow or green LEDs, the tower lamp also has a loud buzzer which we only turned on for 100ms because its SUPER LOUD and we don’t want to annoy anyone around 🙂 – video.
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.
