A large network of undersea telecommunications cables crisscrosses the planet under the water and on land. The cables carry data all around the world, and many of them are owned by Amazon, Facebook, Google, and Microsoft. A team of researchers from UC Berkeley, Berkeley Lab, the Monterey Bay Aquarium, and Rice University has described an experiment that turned 20km of undersea fiber-optic cable into the equivalent of 10,000 seismic stations.
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.
