I like to point out that people will be using a flashing LED for the
rest of their time playing with these things--today it indicates their
Arduino software & hardware is set up and working correctly; tomorrow
it may mean their signal has successfully reached their satellite,
bounced off the moon and come back to them... And the buzz is always
the same. :) Soon followed by "Oh, but what happens if I change

It's like you're reading my mind. :)

The sequence I use is: on-board LED flash; LED blink speed change;
connecting a bread board with LED; connecting a bread board & button;
and, (optional) making button control LED. That's normally enough
(with a bit of overview/background) to fill 3 hours with ~30 mostly
software developer adults.

I think it's beneficial to have a quick selection of 5-10 full screen
photo slides showing projects like the Botanicalls, light-up cycling
jacket and whatever turned up on the Make blog that day. :) Just to
give people an idea where they might go...

All the best! We'll be interested to hear your post-teaching report. :)
