iOS Sensor Apps with Arduino: Wiring the iPhone and iPad into the Internet of Things

Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you’ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You’ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.

iOS processes data from its own onboard sensors, and now you can extend its reach with this simple, low...
