Arduino Uno to Control PWM Fans?

I merely used to explain how I originally thought how it was going to work. However, since jbarchuk pointed me to some other posts, I now understand that was not the case. And I added a question mark to please your needs.

Makes me realize again how much some people like pick on every tiny mistake others make.

Okay, I didn't include a diagram/schematic. Not only is this my first post, but I literally just started into making electronics (for lack of a better term onhand, don't start complaining about that too) and making a schematic didn't cross my mind. I just barely managed to remember most of the basic signs in schematics.

I don't know what happened to you, but you seriously need a change in attitude. I probably going to never use this forum again if most of the members are like you. Luckily for me, there are many alternatives.
