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!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
