I have the above code on an Adafruit Flora, with two sets of lights connected. If both sets of lights are powered, after an amount of time the program freezes until I disconnect the power from one of the lights, where after a few seconds it then starts back up again. I've had similar happen with the Neopixel library as well.
I'm guessing this is a memory issue but I'm not sure how to go about fixing it - I'm not familiar with C++, which means I've been struggling to work out what to search for and getting a lot of information on memory management that seems to not be applicable to a basic set of loops. Where should I be looking? Is it something like I need to be deleting the memory allocation for the variables used in the loops each time?
