When we think about renewable energy, we think of rolling fields with windmills or industrial rooftops covered in silicon solar panels designed by human engineers in high-tech labs. As engineers work to make energy systems more efficient and affordable, some are finding inspiration in nature.
Organisms and natural systems have had some 3.8 billion years to evolve. Because energy is the currency of life, in the process they have come up with energy-efficient ways to function. From more productive wind turbines to strategic solar arrays, there’s a lot we can learn from nature about improving energy production and use.
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.
