I have a stepper motor I want to run with very quick blink pulses but I want a way to do it without blocking the code, I know about blink without delay but I'm unsure it can do what I want since I first want it to blink with a certain delay, then blink with another delay in the code. example:
long interval = 1000;
at one point of the code and
long interval = 500;
at another.
I hope my question makes sense.
You'll notice in the blink without delay example that the variable "interval" is fixed at 1000.
It is a variable so you can give it any value you like.
To clarify it a bit more, I'd like it to run at the variable of 1000 for around 3 seconds then switch to 500. Or run at 1000 for 3 seconds then 500 for a set amount of time then 200 then go back to 1000.
You'll have to define "around 3 seconds" a little better for the compiler, but there's nothing to stop you assigning any value you want to "interval" at any time.
So I can change the interval inside the loop? How do I do that?
With a simple assignment - it's a variable
I think I get, I just call long interval = 700; inside the loop if I want to change it, but how do I time it? How do I get it to keep track of how long it has been blinking before changing.
I just call long interval = 700;
That looks to me like you're creating a new variable call "interval", which probably isn't what you want.
How do I get it to keep track of how long it has been blinking before changing.
I have no idea - I can't see your code - but it probably involves some calls to "millis()"
The blink without delay example demonstrates how to run code after an interval. That code can do whatever you want, including changing the variables that control the timing of that piece of code, or variables that affect timing of other pieces of code.
