Since then, the rise of Raspberry Pi has been inexorable, with more than seven million units sold. This fully customisable and programmable computer, no larger than a credit card and only slightly thicker, can be used for everything from controlling the lights in your garage to learning how to become a software developer. In Syria it has been used to create local radio transmitters, able to broadcast messages to towns within a range of up to six kilometres, disseminating information about nearby skirmishes and essential supplies.
The Pi computer has been used to take weather balloons to the edge of space – its four AA batteries draw just enough current to stop the device from freezing – enabling schoolchildren to send teddy bears into the stratosphere to take photographs of the curvature of the planet. It can even broadcast its position by GPS, enabling those children to locate the device when it floats back to Earth. It doesn’t matter too much if it is lost, because it costs as little as £5 in its most basic form. This year, the foundation gave away a basic Raspberry Pi on the front of the MagPi, an affiliated magazine that teaches readers how, among other things, to program a football game from scratch.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
