ake the Electrical Type for pins for GND. Someone told me to make the pins on my Symbols Power Input and I did that, but it trns out that some of them have to be Power Output. Consider the standard (from library conn) Barrel Jack, one of these

I suggest you read this FAQ post again very carefully: Electrical type of schematic symbol pins (KiCad 4 and KiCad 5)
Especially the section about power pins.

It might also be a good idea to read a book or two about the basic of electronics. At least the simple stuff like what is current, what do we mean with voltage, how is power transmitted. And yes all of this requires the understanding of some basic mathematical models.
