 For the circuit Python Parsec, what I wanted to do was show you how to constrain a range of numbers to a minimum and a maximum that's useful to you. What I have here is a circuit playground express with a potentiometer hooked up as an analog input, so it's being read on pin A2 here and it's got power and ground, basically acts as a voltage divider. If you look at the code, I'm importing the things that matter here, the board, so I get pin definitions and analog IO, I actually don't need time in there, I was using that earlier, I'm not now. What I do is I set up that analog pin, pin A2, to be an analog input that I can read with the phrase analog in, that's a variable name, equals analog IO dot analog in board dot A2. And inside of my main loop, what I'm doing is creating a variable called knob, which is using this key phrase, min max analog in value, comma, my minimum number, I want it to have a minimum of 20,000 and my maximum, I want it to have a maximum of 50,000. So if you watch here when I turn this knob, it's got a little bit of a dead zone at the beginning and then it grabs it at that 20,000 mark and it goes up to, it hits 50,000 and stops there. So what this allows me to do is ignore some of that sort of little sloppy beginning and end zone there, which can vary from potentiometer to potentiometer and instead I use the nice meaty center where it's predictable. And so that is how you can constrain a set of values using min max inside of circuit Python. And that is your circuit Python Persec.
