Most microcontroller projects have an on/off switch or some quick way to cut power, while computers like the Raspberry Pi require an orderly shutdown procedure…otherwise the SD card may become corrupted and the system will no longer boot.
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.

Thanks for the article. I’m surprised in the 14+ years since I wrote my Embedded Linux book that RO operation isn’t an installable package or standard option (particularly with millions running raspberry pis, beaglebones,g etc). People are still doing this by hand, or a script in this case.
