How is a PCB Manufactured

How does a circuit board get made? Maybe you have a rough idea of the steps involved: someone designs a schematic, which is made into a layout for the physical design, which then gets exported into the machine-readable files. Somewhere after this, those files are sent to a printed circuit board (PCB) manufacturer, or the “board house”, who manufactures the boards somehow and then ship them .

Choosing the right transistor for a switching circuit

When choosing the right transistor for this job, first I'll eliminate the PNP transistors. They're a bit more complicated to use in your case. As you said, for a PNP transistor, active high becomes active low, meaning the transistor will switch on when you apply 0V from your Arduino, but it won't switch off when you apply 5V from the Arduino.
