Difference between pins 13, 12, 11...

Using Arduino Motors, Mechanics, Power and CNC

Hi,
I follow the following circuit (see picture).
When the pin is changed and set to 13, the motor turns. However, when the pin is changed and set to 12, 11, 10... or 1, the motor does not turn.

Anyone knows why?

um cause there is nothing connected to any other pins?

can you expand on the question

Or your coding addresses pin 13

Erm, because your code is wrong? Failed to call pinMode() for the right pin? Post the code perhaps?
