Here I provide an example library to do that. One efficient way to communicate between Arduino ... the PIN code, the default PIN is 8888, feel free the change it later at line 70 of bluetooth ...

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 ...

The example Bluetooth sketches from the Arduino website worked quite well, and it was easy to figure out how to utilize the code to build your own. Native 3.3v with 5V Tolerance: A huge part of ...

Resist the urge to solder the Bluetooth board in–since it talks on the same port as the Arduino uses for programming, you’ll have to remove it before uploading new code. If you need help ...
