Arduino Programming Pro

Program and test Arduino remotely using Smartphone without downloading code.
[Features]
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.
