The phone uses an app that talks to the Arduino via Bluetooth, which means the Arduino needs a Bluetooth module. The Arduino controls what amounts to an upside-down 3D printer.

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.

The Arduino can be a bit of a gateway board. You start with an Uno, then a shield, then another. Before you know it, you have an entire collection of shields. This is the problem 1Sheeld wants to s… ...

recycling the most ubiquitous cellphone the year 2003 had to offer The watch itself runs off an Arduino board, and manages to fit a Bluetooth module and 3.7v battery into the 3D-printed watch case.

There is no any hack, or ingame modding.Its only kayboard and mouse emulating with phone and arduino. This app comes only from an idea “maybe can i control the ingame phone”.

The Coin Arduino-BLE kit is designed to simply that by offering a pre-rolled solution, completely with open-source software that will go up on Github in December, which is when the boards should ship.

Primo will include Bluetooth LE (low energy), NFC, Wi-Fi, and infrared built-in — you typically need a “shield” add-on to get these features.
