Another great thing about the Propeller is that you can very
quickly test new code by downloading straight to its RAM
(all programs run from RAM). This lets us make and test
changes very easily. We can do this by pressing the F10
key in the IDE. Once everything is the way we like it, we
can do a permananet download of the final code with F11.
Well, there you have it; a fun Halloween prop and a
neat way to safely simulate flames. Want a hellish pit of
burning coals in your Halloween display? No problem! Just
use red and orange LEDs and set the flicker algorithm to
low-and-slow. With a little imagination and a bit of fine-tuning of the flicker parameters, you can simulate most
anything that’s “burning.” Happy Halloween! NV
