@peekay123 Unfortunately I can’t seem to get anywhere with it! All I seem to get is white flickering and flashes of green up and down. I tried commenting out all the example code in an attempt to get it to just start with switched off LEDs but even with all the subroutines commented out in the main loop, I get the same effect.
Does the fact that the arduino uses a PWM port but the spark ports userd here aren’t PWM make any difference?, (I presume for this library PWM doesn’t come into it so the answer is no)
I’ve retested the strip with the original supplied controller and it is still capable of functioning normally so the strip is fine.
I’m not certain what the cpu settings in the code do (if anything, as they don’t seem to be defined) and also, as for the 50 LEDs, I had read on a different amazon page for what looked like to be the same product, a review that said the LEDs were only addressable in groups of 3. I’m still guessing that doesn’t matter in this instance though since I should still expect some of the LEDs to start in the off state if set to 0,0,0.
One final question, if I use the cloud version of pre-existing SparkIntervalTimer library rather than the one on your Git repository, does that make a difference? Is your library the same or somehow modified? I only ask because now that I have it compiling and flashing from the cloud, I do find it easier to make changes to the code and re-flash that way when I am not powered from USB.
Really do appreciate all the time you are giving this
