The emitter is as at 23 d
The collector is at 22b
I just realized that the cathode of the diode is facing the wrong direction. I’m going to fix it but the battery is charging at the moment so I won’t know if this fixes the problem until later
The right part of the motor is negative and the left side is positive
That didn’t fix the problem
Which one of the white ones is positive?ah91086:
The white wires connect to the positive and negative ends
The red, the one on the right
Try to use different colors for wires going to Vcc and GND, and to positive and negative battery terminals. So you know clearly which is which. If you make a mistake and connect something to the wrong one, it can be fatal for the parts. Black is usually ground or battery minus. So all wires sticking into the blue rail on the breadboard can be black. (if you have that ofcourse.) Red is usually positive battery terminal. As your Vcc is different from RAW I would use a different color for that also.
Still looking for the fault.

The right part of the motor is negative and the left side is positive
I disagree with the right part of the motor being negative in this picture. If I look at the datasheet from the link you gave in the very first posts, looking at the back of the motor with the wide part upwards, the left side would be positive. If I look at this picture, it would seem that that is the right connection in this image. And the diode is oriented correctly for that in this picture.
Can you make another picture from the back of the motor to be sure. Make sure the black ring of the diode, and the cross section of the motor is in good view. Please hold on trying to fix it yet. I’m not done with fault finding.
I don’t have access to it right now so this is the best I can do
I don’t have them with me right now so this is the best I can do
As soon as I get home I’ll send better, more clear pictures
I think I found the cause why the motor is not turning. You shorted it by connecting both leads in the same row (23) of 5 holes (G and H). See the red ‘ellipse’ surrounding it. Current goes directly from the orange Vcc wire to the blue wire, bypassing the motor, into the transistor. The holes for A,B,C,D and E are all connected to each other. And so is F,G,H,I and J connected to each other. They are disconnected from the rows adjacent. You’ll have to put the negative motor lead into another row (like 24), in which the blue wire going to the transistor collector should also by stuck into. You probably have to put the diode back in the previous orientation if my conclusion of the previous post is correct.
You did the same with the resistor in row 29 in G and H. It is shorted across it’s leads, and therefore doesn’t function as a current limiting resistor anymore. Stick the red wire and the adjacent lead of the resistor in row 30 for example.
Hopefully nothing burned out (the transistor or even pin 13 could be damaged). Let’s be safe. Before you power it on, show another photo of your changes. There seems to be a led near pin 10 of the arduino pro mini which would be the ‘pin 13 LED’ used for the blinking program. If that works then the arduino pin 13 is ok.

Solder these male pins into the holes on both sides of the arduino. Stick them in from under the board, and solder them on the top. But make the programming header at the back stick out on the upper side (and solder them from below), or it won’t fit into the breadboard anymore. (right angled male header pins might be better for those so it doesn’t have to stand up) Though I’m not sure if the bluetooth module has female header delivered with it.
I noticed you have the wires only sticking in the holes and bent around it. That is not a secure connection and could easily have caused those earlier disconnections. Using these headers you can stick the arduino in the breadboard and be sure of a good connection. You might use a bit less solder though. I understand you are a beginner in this. But those blobs on the motor and diode are a bit nasty. Watch a few solder tutorials on youtube if you have a problems with it. Is that un-leaded solder perhaps? That is harder to make nice solder joints with than leaded-solder.
