 For the Circuit Python Parsec today, I wanted to show how you can use some loops and the range command in order to create LED patterns. And the way this works is that I'm importing Neopixel, I'm creating some color definitions, and then I have a ring of 24 Neopixels. Then I set a couple of variables called even interval and odd interval. And then here is where I am lighting them up. For example, if I just turn these off and hit save, what you're going to see is just the even pixels, every other one is being lit up. So if I say, let's light up every one of them, my interval is a step size of one. And now we can go down to, let's say three, we'll get every third one lit. And you can add on top of this. So let's say I want sort of a Christmas holiday wreath kind of look, I will set every pixel to green, but then every third pixel will get set to red. So here you can see it with every pixel as green. And then second later, I'm drawing in that second set of them, and that's every third pixel. So now if I change that, how about every sixth pixel is going to be that odd color of red. Give it a second, I'm giving a little pause, and there we go. So the way this is working is that for each of my little ranges of neopixels, I have this for loop for I in range, and then I have the start and stop number of LEDs, and then the interval, which is the step size, it runs through and it sets those to green. And then only at the end does it do my little show, which lights them all up. If we remove this sleep here, and let's set that number back down to how about every other one. Now we're going to get every other one lit up red, and it happens instantaneously. And so this is how you can use a loop along with the range command in order to light up patterns of neopixels. And that is your Circuit Python Parsec.
