 For the CircuitPython Parsec today, I wanted to show you how you can use a step size inside of a range when you're looping through things in order to change the increments you use in the loop. Often when we use the 4I in range and then some number, the default is to increment one value at a time. This is a really common way to sweep a value up. Say you're bringing up the PWM value of an LED, you can loop through it with 4I in range and then a number. But you can also use 4I in range, start value, stop value, and size value. What that does is allow you to say, here's where I'm going to start, here's where I'm going to stop, so that's the range. Then the actual size of the steps, so it'd be like plus I equals I plus 2, I equals I plus 2, I equals I plus 2, so it keeps incrementing up by 2s or 3s or 4s or whatever you need. I have some numbers printing out when I press a button on the circuit playground express. When I press the B button, you'll see it's going to increase that step value, so now I'm increasing by 2 every time through. Now I'm going by 3, so 0, 3, 6, 9, 12, and so on. Now I'll go up by 4s. The way to do this is right here in the main loop. When I press the button, one of the things that's happening here is for I in range, start value, I have that set to 0, stop value, I have that set to 41, and the step value or size of the steps is 1 to begin with, but every time I press this button, I'm increasing the number there, so I'm going through different values. I can also decrease that using the other button. That is how you can use the range command with start, stop, and step in order to change how you loop through a set of values. That is your circuit python parsec.
