LED strip: j = (j + 1) % 256 // current iteration of the light cycleįor(int i=0 i< strip. Here are the two pieces of code by themselves, which I've tested in isolation and confirmed that they work properly: A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages. And our loop() is only 5 lines of code Next well add a button so we can interact with. What I'd like to do is have the LED strip continuously cycle through a rainbow of colors, and the light sensor will adjust the brightness of the LED strip based on the ambient light level. Programming languages provide various control structures that allow for more complicated execution paths. Now we have 5 independent tasks running non-stop with no interference. I can't make a shortcut for a smart solution with a single loop, it is a double loop. A light sensor that can detect the ambient light level.Is that what you're getting Your question is incomplete. I would expect this code to print: either 'inside while loop' (if pin 2 is false) or nothing, followed by 'Break.' over and over again.
