Why simply play music or go online when you can use your iPhone or iPad for some really fun projects, such as building a metal detector, hacking a radio control truck, or tracking a model rocket in flight? Learn how to build these and other cool things by using iOS device sensors and inexpensive hardware such as Arduino and a Bluetooth Low Energy (LE) Shield.

This hands-on book shows you how to write simple applications with techBASIC, an Apple-approved development environment that runs on iOS devices. With just a few lines of code, you can write apps directly on your Apple device and have it interact with other hardware.

• Build a metal detector with the iOS magnetometer
• Use the HiJack hardware platform to create a plant moisture sensor
• Put your iPhone on a small rocket to collect acceleration and rotation data
• Hack a radio control truck with Arduino and Bluetooth LE
• Create an arcade game with an iPad controller and two iPhone paddles
• Control a candy machine with an iOS device, a micro servo, and a WiFi connection
