The following schematic shows the wiring of the Arduino Nano and the ULN2003 Driver Board with the 28BYJ-48 5V Stepper Motor.
I use the Prototype PCB to create the user interface control board, with the dimensions of 15mm x 40mm, then arrange the push buttons and the 10K resistors as shown on the following picture.
After all compoents are connected, I arrange everithing in side the enclosure_box.stl, (I use hot glue to secure the cables before installing the components on the box) and use the enclosure_arduino_clamp.stl to hold the Arduino Nano and use three Phillips screws (2-28 x 3/8 BC-0206LPP) to secure the ULN2003 Driver Board as shon on the picture below, notice the Arduino Nano's pins are facing up.
The code I use, to control the steper motor using the ULN2003 and the Arduino Nano is on the file: "Motorized_SMD_Reel_Loader.ino" and can be cutomized to expand the functionality of the Motorized SMD Reel Loader.
