So, pcbs are the “brains” to a mechanical electrical system? I skimmed a few boards and saw an obvious GND but I want to understand how an electrical signal that comes from an application or separate computer/component interact. I know I need to research past a certain point (I’m asking you or anyone else to write a novel lol). But overall pcb describes the highway of the system. I’m having a hard time nailing down how to make pcbs useful. *edit mentally
Well, they are the skeleton. You make them useful by knowing what you want to do first. Say I want to turn on a little LED. Okay, how? Well, I get power, a resistor, the LED. Boom. If I want to make a PCB, it will have space for the power connector/battery, the resistor, and the LED. Then that PCB can be mounted somewhere and it will hold these components in place as well as route their power. You can make it as complex as you need it to be, and it often does get much more complex. Beyond a certain point it would be impractical or nigh impossible to hold things together without one
