Hmmm..... what to write?

Now there's the question - what to write? And can I separate the writing part from the playing-around-with-the-software part?

Early chunks look hard - teaching complex programming constructs from scratch to people with unknown background. But the later parts look hard too - heavy maths & trigonometry. I suppose I could write about Bezier functions if I knew what they were... But the later parts would encourage me to learn, and interact more deeply with the software.

I'm drawn both ways. But I think I'd like to start near the beginning. I'm drawn to the challenges of clear teaching of complex topics. So I've volunteered to write chunk 12 "Arrays and for statements". I rather fancy seeing if I can teach that clearly in 2500 words. Plus, I should be able to make a start without waiting for the book.

Meanwhile, I'm still frittering time away looking at the examples, and also at the Arduino board, and thinking of what applications they open up for me.
