Smartphone and Tablet Hacks

Smartphones and tablets are highly integrated mini computers, and even older models are often a lot more powerful than typical hobby systems such as Arduino and Raspberry Pi. Portable devices have built-in power, cellular radio, Wi-Fi and Bluetooth, and also offer a high-resolution touchscreen. All they lack are freely programmable I/O ports for implementing your own apps.

In this book, Klaus Dembowski shows you how to add programmable interfaces to mobile devices. He covers the basics of electronic components and metering techniques so that the sensors and circuits you add deliver reliable results.

The topics Dembowski discusses cover the entire signal processing chain, from basic sensors to the “internet of things”, which relies heavily on wireless data transmission technology. The apps you need to communicate with the hardware are available for download from the book’s website.
