New York City’s squirrels have been through a lot. According to Sadie Stein at New York magazine, deforestation around the city in the early 1800s pretty much wiped out the squirrel population. When a pet squirrel did escape in 1856, it was such a novelty that it attracted a crowd of hundreds that had to be dispersed by the cops.
In 1877 and 1878, between 60 to 70 squirrels were released in Central Park. By 1883, the population rebounded a little too well; an estimated 1,500 squirrels reportedly destroyed trees and other vegetation, leading the city to authorize a squirrel hunt. Over the next hundred years or so, the squirrel and the park came more into balance, and now, as the new project shows, the urban forest comfortably supports more than 2,000 of the critters.
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.
