The world faces an urgent task to rapidly reduce greenhouse gas emissions effectively to zero as soon as possible to stop climate change. This will mean a fundamental shift away from fossil fuels as our primary source of energy, and we will have to make this transformation while striving to make people’s lives better around the world.
The level of carbon dioxide in the atmosphere has been increasing since the Industrial Revolution, mainly due to our burning of fossil fuels: coal, oil and natural gas. The current concentration of carbon dioxide is about 415 parts per million (414.63 ppm on 4 May 2021), about 48 per cent higher than its pre-industrial level of 280 parts per million.
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.
