Chemical engineer Paul Dauenhauer of the University of Minnesota has dedicated his career to revolutionizing the materials we rely on most. He’s worked to derive crucial “chemical building blocks” from renewable resources that can be used to manufacture existing products, as well as create entirely new alternatives.
Unlike materials like fallen leaves or animal waste, which decompose easily with help from microbes, the plastics we use today can’t break down as well. And they pose another environmental threat because of the way fossil fuels, whose derivatives are used to create many consumer products, including plastics, are extracted from the earth.
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.
