user63723: My understanding of the H-bridge is, that activating in1 or in2 will direct the 12V current to the motor, so it either spins right/left. Not that in1 or in2 is the actual current passing through to the 12V motor.
These are the schematics.
I am trying to activate the H-bridge and the 12V motor by powering In1 with digital 2 from my Arduino.
The power outlet is an universal adapter connected to my wall outlet, which then goes to a breadboard power supply.
I don't have a functioning multimeter, so I cannot measure the exact current going through, but I do know, that if I place in1 in the power outlet's Vout the 12V motor spins.
Other than that, I do not have much information, and I would like to ask you guys for help as to why, the 12V motor doesn't spin when I power in1?


user63723: There was no common GND between the H-Bridge and the Arduino.
The question has been solved.
