What code did you upload?
Post this code as a code-section like shown in this tutorial
How did you upload this code to what exact type of microcontroller?
From your pictures nobody can conclude what is connected to what.
You will have to draw a schematic how you have connected the wires.
At least describe each wire as
starts on microcontroller-IO-pin named "...." is connected to IO-pin named "...." at the steppermotordriver.
