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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
