Arduino Remote Control using Phone Bluetooth.

To see how to use this App click here. It is tutorial with a sample project. You can use the App for your own projects.

For this App to work you need to put a Arduino sketch in your Arduino device. To download the Arduino Sketch click here.

Learn various Arduino Commands by Chatting with Arduino. Program and set Arduino Pin functions by sending commands remotely without downloading code.

App is used to program (change pin settings) of Arduino remotely using Bluetooth. You do not need to download programs to change pin settings like pin mode. You can do it remotely using this app.

Its a great tool to learn Arduino in the most fun way by chatting with Arduino.

You can use the sample sketch given here. This sketch can be customized/changed to suit your needs, language and enhance your experience.
