[Features]
App is a instant messenger using which you can send commands as messages to Arduino to do certain functions and respond accordingly. It has predefined messages (Arduino functions/commands) like pinMode, digitalWrite etc. and user only has to tap on the pin number to construct messages.

Its a great tool to to learn Arduino in the most fun way by chatting with Arduino. Many Arduino sketches(programs) can be developed around this app to enhance learning experience. Using this app is a good interactive way of learning machines. It is also used to quickly test Arduino and Arduino based machines.

It uses Bluetooth for communication. You will need a Arduino with Bluetooth. You can find many tutorials to connect Bluetooth like HC-05 to Arduino. You also need to upload in Arduino the sample sketch given here. This sketch can be customized/changed to suit your needs, language and enhance your experience.

[Arduino Sketch]

/******sketch for WhatsUpArduino App*******/

[Plus Button]
The Plus '+' button opens system Bluetooth settings to scan Bluetooth devices and 'pair' them with mobile devices.

[Info Button]
The info button 'i' connects to 'Language Reference' page on Arduino website.
