Propeller Flip

I read Jim Arlow's great article about this device with considerable interest. It made me want to get one to play with!
I did find one thing about BlocklyProp a bit confusing at first, and I suspect it might trip up some others. Throughout the article in the BP (BlocklyProp) examples it refers to the I/O pins as "PIN 16" and so on. This is sort of an unfortunate semantic choice by BP IMHO as I initially interpreted that to mean pin-16 of the package. Not so!!! I/O port bit 16 is connected to package pin 21 as the wiring diagram correctly indicates. Just remember, when using BP that a "PIN" number is not the same as the package "pin" number!
