I'm starting my hobby electronics journey. I know how to read all the symbols and know how to solder. But I'm a bit confused with reading schematics that have multiple GND and the difference between VCC vs +5v.
Please take a look at this schematic.
Where do the ground points physical connect to?
Do they symbolize the negative terminal on power source and therefore all GND points should connect to each other some how?
There are VCC points and +5v points. Are they the same? If not, where do the wires connect to?
Which power adapter can I use to power this station? THe schematics have +5v. If I got a laptop charger that was 19v 60watts 4amps, how would I use it to power the +5volts which is less than 19v of the charger?
Also from one power adapter how would it get 15v ac and 9v ac power from?
I'm trying to replicate this soldering station. here.
