This is the most comprehensive graphical programming and developing tool based on Arduino. WhenDo is the most sufficient way to learn about Arduino and every basic programming logic.

WhenDo is compatible with all the Arduino chips that have Bluetooth 4.0 module .

Significant Features:

1. Graphical programming
In this graphical programming language, user just need to drag condition and execute blocks and freely combine them. This development tool applies many amusing functions that the Arduino can accomplish in WhenDo.

2. Clear and meticulous logic
Each sentence involves three elements: When block ( condition setting), Centre Node (combine When & Do block) and Do block ( execute setting ). Besides, the whole interactive User Interference environment is a big loop, which repeatedly run the program statements.

3. Cloud server compile
Excellent file transfer and compile based on a Ubuntu server.
Remote access to various libraries to improve its capability.

4. BLE download
Wireless download the program through blueTooth 4.0 Arduino devices.
