I know of very few programmers who still flow-chart (except in PowerPoint slides for managers and other non-technical types)- most sketch code in either C or pseudocode.Far more important these days is showing object relationships, using UML or similar notations.
You're aware that it turns the flowchart directly into code, right ? and that 99% of arduino users are not professional programmes ?
I've said that I am a noob but if some PCAs come with this kind of programming interface then it means that it does make some sense
