That’s certainly the case with Carrie Norin, an evolutionary biologist who teaches science at Princeton Day School, in New Jersey. Her photographs of the microscopic world reveal a spectacular universe of form and color we would never otherwise notice or have access to. They’re not simply striking to look at, however; they’re also proof that the invisible, relentless hand of evolution by natural selection is responsible for the seemingly infinite variety of life forms on our planet
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.
