Running two applications at the same time simultaneously

Hello everyone,
I've recently started messing around with arduino and I'm really enjoying it :slight_smile: . So far I've reached a point where I would like to combine two sketches at the same time and put them as one sketch but I wasn't able to do so. For example , I would like to flash and led and at the same time activate a servo motor at different outputs. So basically these two functions each have their own code and I would like to combine them into one.
Thank you.

And yet, you didn't think anyone would want to see your code to help you.
