The current focus of the Urban Greenprint is to generate building design techniques and use of materials that take cues from our local natural ecosystems, including methods of construction that encourage evaporation.
Remember the mist you feel on your face when you walk through a coniferous forest in the rain? The layered and textured canopies of red cedars and other conifers break up big raindrops into fine droplets that readily evaporate. Tree trunks, lichen, and moss hold onto moisture, as does the detritus on the forest floor and the rich organics in the soil itself. Textures, layers, and permeability all contribute to a system that holds water like a sponge until it infiltrates or evaporates.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
