This Bluetooth module ties directly into the Tx and Rx lines of the Arduino so a wireless serial connection between an Android device can be established.

The Arduino gets a Bluetooth attachment and a set of code. Then you'll need Android Meets Robots, an app that lets you pair voice recognition with any Bluetooth module.

This is a simple project. It uses an Android device to switch an LED driven by the Arduino. Connectivity is provided by the Bluetooth module inserted in the breadboard. But one look at the UI on ...

This project incorporates communication between an Android Phone and the Arduino using Bluetooth. The basic functionality includes taking messages from an android phone, displaying them on an LCD ...

Makers, developers and hobbyists that are looking for a low-cost Bluetooth Arduino compatible micro controller that can be controlled and programmed ...

Joe Desbonnet combined an Arduino microcontroller with a magnetic coil to create what he calls the “Poor Man’s NFC”.

Now, a project called UDOO ("you do") seeks to bring the best elements of Raspberry Pi and Arduino together into a single mini-PC that can run either Android or Linux.

The $22 kit includes an Arduino-BLE board and 6-pin header that should be fairly broadly applicable for building Arduino-based hardware that can communicate with iOS devices.

Arduino, the DIY nerd's best friend, gets a little love from Google with the Android Open Accessory Development Kit.

Well tech tinkerer Joe Desbonnet has whipped up what he dubs "poor man's NFC" using an Arduino, some magnet wire, and any compass-equipped Android smartphone (which is almost all of them).
