THIS IS A PROJECT BOOK that marries together the simple-to-use microcontroller boards (Arduino) and the world of Android mobile phones and tablet computers.
The book contains detailed instructions for constructing various projects that use Arduino and Android devices. Some of the projects, such as the Geiger Counter and the Ultrasonic Distance Meter, are essentially electronic accessories for your Android phone.
