Upton, the founder and chief executive of the 10-employee foundation in Cambridge, England, says he grew convinced that more kids needed introductory programming lessons (or, in some cases, remedial ones) while he was running the computer science department at St. John’s College at Cambridge. While interviewing high school students who had applied to the school, he says, he often found them less prepared in the computer science field than he had expected. “We were finding we had to teach people things we assumed they already knew,” says Upton.
The professor started developing his single-board computer in 2006 and released the first version in 2012 after six years of prototyping. B+, the single-board computer’s third commercial version, went on sale last month for $35. Customers can purchase the device from the Raspberry Pi website or such product sites as Adafruit.
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.
