septillion:
If you going to use solenoids, do note the frequency of pin 5 and 6 is different from the rest and not easy changeable.But I will look into it tomorrow. I will need to dig up an Arduino :
Still unpacking boxes after moving...
Can you try the second piece as well?
So this is pretty much the extent of what happens with both pieces of code.
The exact thing happens with the second code. One LED phases in then out. No loops and no signs of any other LEDs.
I also moved the pins to 9,10,11 like your code has, but no avail.
