Binary counters.

I was looking around on making binary counters (specifically 4bit counters) but I'm quite not getting how they work in Arduino.
I've been looking at source codes of other people and their 4 bit binary counters but I'm not understanding fully why they work.
Can anyone explain to me in terms of the loop method how/why they work as such?

Yeah, I would like some help too. I just started and I'm a bit confused because it's like C a bit.

Hi, post a sample of the program you are looking at and we will explain.
Tom… :slight_smile:

Please don't use scrolling text. It's totally pointless and doesn't give a good impression.
