Arduino Flow Diagram Programming

Hi Guys

I am new here so if I am asking something already done to death I apologise because despite looking I couldn't find an obvious reference to the subject.

Is anyone aware of or interested in a simple Flow Diagram based IDE for educational purposes ??

I have used such for teaching/introducing kids to PIC based microcontrolers but would like to do similar with Arduino/Atmel based microcontrolers.

The code and IDE as it stands is great but a little too complex for introductory/school kids level.



I discovered this blog post a while ago but haven't looked into it:
