delay()? from a newbie

Projects Programming
1

Being a 67 year old "newbie" to arduino and a flight sim builder/enthusiast has lead me in some pretty deep subjects in trying to advance my current flight sim build. I've tried many different applications to aid me in this and some have worked and some have not. I've been working on my current simulator for almost 2 years now and I can see the end of the tunnel. I've now started following the Arduino path and how it may be able to help me complete this project.
I've just recently started the "link2fs" path only realizing this should have been my first path. Anyway, I'm not yet quite familiar with all Arduino programming, but recently have had some questions regarding a sketch that will help do what I'm currently working on (NAV/COM radio). In looking at the sketch I'm seeing something I'm not sure what it is saying. It's a simple "delay ()" but it has within the brackets the number 11. My question is what does that mean? when I'm used to milliseconds within the brackets.
After that I'm sure there will be some other things that I have 0 knowledge about, but I will do what I can to learn. I am an engineer, but retired for the past 7 years, so I'm learning much of this on my own.

Any assistance on this would be greatly appreciated.

and Thank you very much,

11 milliseconds?

Welcome to the forums Mike.

Thanks for the help. I know it was a simple question regarding delays, but I was not accustom to see an 11 within the brackets and it didn't seem like 11 milliseconds would be worth even using it.

Thanks again to all

An Arduino can do 176,000 instructions in 11 millisecs. Of course they are not much use if it is just going round in a circle waiting for the delay() period to end.
