Today Mr. Postman brought me, from SparkFun, an Arduino Due.
I downloaded and ran arduino-1.5.1r2-windows.zip(beta) and it runs just
fine (on Vista64) both Blink and one of my apps.
The Due is physically larger than Uno but it seems to be quite compatible
otherwise, except of course for speed, capacity, and number of pins.
Also Mr. Postman brought me a leaflabs Maple and some other toys, but
that's to be a different thread.
See you-all at show-and-tell at our next meeting.
