Never mind 20 million Google+ users. Since 2008 there have been more ‘things’ connected to the internet than there are people on the earth: by 2050 there will be 50 billion connected devices — from cattle with wireless sensors that report when a cow is sick or pregnant, to implanted defibrillators that upload diagnostic information and heart rate patterns, to bridges that record every time a boat sails underneath them.
There are ambitious ideas about monitoring the weather, detecting when buildings have been affected by earthquakes, predicting traffic jams and avoiding accidents by having cars tell each other where they are (something Ford and Toyota are working on together), spotting epidemics before they start — all by building up massive, real-time data sets to analyse and act on.
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.
