In the spirit of a nice afternoon project, I’d encourage you to use what’s laying around if it’s close to the specs here. But if you’re going to buy all these parts ahead of time like I do, hopefully it will help to use the product links below. While I love Amazon, please try and support great suppliers like Adafruit, who have a great forum community, customer service and tutorial section!
Raspberry Pi Model B (Although a Model A might work, it wasn’t used for this build.) Get it from Adafruit or Amazon.
5VDC USB Power Supply (For some reason, I had 2 of these in the bottom of a box, but this one would work great too.)
16GB SDHC Memory Card (I used this one, but feel free to use whatever you have laying around- this tutorial might not work with smaller density cards, so beware.)
HDMI Monitor and HDMI Cable (I happen to have this one, but anyone should do.)
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
