Sorry for the beginner question, but I am very confused about which is easiest when working with an Arduino for things like 7-segment displays... common cathode or common anode? I don't seem to be able to find much helpful information with my searches to differentiate between the two. A little addit…

common cathode/common anode confusion

It is much easer to use common anode, there are many more support for this.
Current sinking is where you connect the anode to +5V and the output switches the ground.
