 For the Circuit Python parsec today, I wanted to show you Blink Without Delay. You may be familiar with Blink Without Delay as one of the seminal Arduino sketches that shows you how to do things without blocking, how to count time and do things on a time interval without blocking the rest of your code. And a way that you can do this inside of Circuit Python is by setting a state of a certain time using time monotonic, which is a clock that's always running, and then comparing the current time monotonic to the last time monotonic. So let me show you the actual demo here. What you can see is I have LEDs blinking on my boards here. I have a feather with a neopixel on it. I have a little rotary encoder, STEMA QT board with a neopixel on it. I also have the board D13 LED. They're all blinking every half second. Now what you notice is those will keep blinking, particularly easy to watch the little pin 13 LED up at the top of the board there. But as that's happening, I'm moving my dial here and changing the colors of the neopixels. You'll notice that nothing is blocking. I can smoothly move between these colors, and it doesn't interrupt that blinking interval there. You can even press and release the button to get a different brightness effect. And the way this is working is you can see key thing. First of all, I've imported the time library. Second of all, right before my code begins, I created a variable called lastTime and made it equal to time monotonic, which is the, hey, what time is it right now, microcontroller? Then in my code, this is the key right here. If time monotonic, which is the current time, minus the last time is greater than whatever interval I want to be blinking or doing my thing at, in this case a half a second is what I set it to, then we'll go ahead and run this code in here that does the little blinking stuff. I am also continuing throughout the code loop to check my position on the encoder and do the neopixel stuff there for color. But this way, these things essentially run without getting in each other's way. And that is a way that you can do a blink without delay inside of CircuitPython. And that is your CircuitPython Parsec.
