What is this “Linux”, anyhow? A gentle introduction to the world’s most popular free OS by Brennen Bearnes @ The Adafruit Learning System.

If you’re starting down the path to learning about electronics or computers, you may have noticed or heard about “Linux” – as in “this dev board is linux-based” or “this wearable runs linux” or “I wrote a linux script to control the barcode scanner”

And you might be wondering Well, what is this “Linux” anyhow? Does it matter to me?  and then maybe you asked someone and you got a long rant about stuff called kernels and bashed shells and how you’re wondering if its corn-related or is some sort of crab.

Being that this question and confusion is inevitable, and we’re getting so many people asking about this mysterious Linux, we at Adafruit thought we’d write up a series of tutorials to help you understand what linux is, when you want linux and how to use it when you do.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

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.
