For about the last 3 years, the de-facto method of accessing physical components via the Raspberry Pi’s GPIO pins has been a Python library called RPi.GPIO, created by Ben Croston, who originally built it to control his beer brewing process. Despite its humble beginnings in a personal hobby project, it’s ended up being used in projects of all shapes and sizes by users around the world, and it has a big presence in education. In the Foundation, we’ve used it in many of our learning resources, and we use it at Picademy, our teacher training course.
Physical computing is one of the most engaging activities for teaching computing, and has plenty of scope in computational thinking, programming skills and logic as well as projects being more relevant to young people (think build a robot vs. sorting arbitrary lists).
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.
