Ladies and gentlemen, if you are like me, you probably have a few raspberry pi. (Piis?) I have found them to be great little Linux development boards supported by a huge community. Whenever I need a net connected microprocessor project, the pi is an easy win. I have used it in internet connected clocks, LED signs, RGB lighting projects and so many other crazy projects. They make a great internet gateway for Arduino projects. This use is the very definition of “embedded”, a raspberry pi with no keyboard, mouse or monitor. It boots, connects and does it’s programmed task. It would be a huge inconvenience to manually configure every one of these starting from a raspbian .img file. Even if your not into electronics, manipulating the SD cards directly will make your life a little easier.
Now would be a great time to introduce my “day job”. I am a professional *NIX system administrator and system architect. So when I see a raspberry pi I see a Linux box. UNIX/Linux systems are very easy to clone, it’s just a pile of files. I will start with some basic theory and how to work with the SD card from the command line. Then, I will introduce you to my scripts which automate the process.
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.
