Can anyone advise a way to reverse the direction of the leds? They always seem to ‘travel’ towards the bottom end.
How you do it might depend a bit on the code. Please put your code on http://gist.github.com and share the link.
Here’s two examples of patterns that can be reversed.
Here’s a routine that has a direction change variable:
That being said, different animations may require this to be done differently. For example, if I were doing sine waves down the strand, then this wouldn’t work at all.
It also might be something as simple as this:
leds[i] = …
leds[ (NUM_LEDS-1) - i ] = …
The easy way to physically flip you LED strip
If you are using For Loops, then you could initialize with the max array value and count down, instead of counting up? Or change arrange indexes to do something like leds[NUM_LEDS-i] = …
