The Raspberry Pi is a full Linux computer that’s about the size of a credit card and sells for $25–$35. It has a 700MHz ARM CPU and 512MB of RAM. Because of its capabilities and its low price, it has become wildly popular with the hobbyist market. Some people have done ingenious things with theirs.
If you’re like me, you’ve toyed with the idea of getting an AirPort Express but the $100 price seemed a bit steep, since all you really wanted to do with it is play audio using AirPlay. Sound familiar?
Well, guess what – you can turn a Raspberry Pi into an AirPlay speaker for around $45. That’s what you’re going to do in this tutorial. By the end of it you’ll have your very own Raspberry Pi AirPlay receiver!
After that, you’ll look further into the usefulness of the Raspberry Pi to iOS developers. Most complex apps need some sort of backend web service and a Raspberry Pi is a perfect server for development or perhaps even a small app. You’ll install the Apache web server, MySQL database and PHP, then use them to create a web service that you can access from an iOS chat app.
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.
