Funky Plank running Mark’s fire code modified to run over 7 parallel strips. Hung a towel over it as a ghetto diffuser

He posted it in this group, that’s where I got it from 
That is Cool! Share code and circuit for parallel connection pleeeeease…
http://pastebin.com/wmy3gt1P is the modified code, nothing crazy.
As for circuit, well it’s just a strip connected to seven different pins on a Teensy 3.1 - you can see how that works in the code.
Is arduino fits for this project?
im messing with your code a little very nice but one question why does it go the opposite way?
Opposite way? It looks right to me, flames go up. If yours is opposite … rotate your string.
lol well on my stip the flames go down with this code instead of up with the original code i dont mind flipping the strip im just tryin to learn why it does that
also what kind of power do you use for your funky plank?
Could you modify the flame so you get one central ‘flame’? The center most strips would be the tallest part of the flame, only varying slightly. Then farthest strips from center would be the shortest parts of the flame. If the ‘sparkles’ could be more unison as they progress up the center part of the flame, it may look terribly realistic. Less individual random ness per vertical matrix strip is what I’m referring to.
You can change the ‘cooling’ value to achieve a shorter flame, but it would have to be done pre-strip to achieve something resembling what you’re wanting.
@Brett_Hansen it has a 20A 5V power supply.
damn that sounds about right lol
About making this one proper flame. You’d have to do something a lot smarter than I did. My guess is run the main loop just once and embed some extra stuff to derive parallel values. Dammit Jim I’m a linguist not a coder, so that’s above my skill level.
How about adding SIN wave function to vary the size of the flame, modify the sparking, heating an cooling. Perhaps the function could center the flame - even shift the center from time to time. @Mark_Kriegsman perhaps even send up some sparks (fireworks)?
