 For the CircuitPython Parsec today, I wanted to show you how to move an object on a display in a circle using sign and cosine. So if you look at my code window here, you can see in CircuitPython, I've got some libraries to import. Most importantly here is math. Bringing in the math library means that we can use sign and cosine. I'm then doing some pretty typical display setup stuff, and I'm making a little box. There's a little five pixel bitmap box that's going to be on screen, and it's green. I will set the center of that to be the center of the display. I will then divide the display width by two and divide the display height by two, and that gives me the center point of the screen. And then I am setting a variable called angle to zero, and I'm choosing the radius of the circle I'm going to move in. And in order to update my display shape on every step to move it in a circle, I'm setting the x and the y based on sign and cosine, which helps us define a circle. So you can here see I'm setting center x and an integer of the radius that I've chosen here, in this case 35, times math.sign, math radians, and the angle. And then for the y, it's center y plus in radius times math cosine math radians angle. We then update that position so it moves it to that spot. We refresh, and then we're updating that angle that we are multiplying by so that on every step we are moving to a new position on that circle. And then we have a little bit of a delay. So what I'm going to do is start up the code again, and you'll see on my screen there, I have this lovely little box that is moving in a really nice smooth circle. We can change things like the radius of that. We can change things like the speed of that. Here we're going to update that to be a little tight radius of 10. Let's see if we can still see it out at 100. That's going to start to get, I think, a little bigger than the screen. Yep, running on and off. But that is one way that you can move an object on a circular path using the math sign and math cosine library. And that is your circuit python parsec.
