Stepper Motor model turntable

SummarySpins an object or model using a stepper motor, and stepper motor driver. Please measure the size of your own motor to check that it fits, and that your motor has 20 teeth. Modified remixes for different motors and number of teeth are welcome. Runs off an Arduino Nano inside the device with the code in the files attached. Feel free to modify the code to your liking. The code is meant for 16 segment steps. The motor is a bit loud, so I dampened the sound with cloth stuffed in between the motor. The Arduino had to be modified with the back pins removed so it could fit. Upload the code first. Pin 13 connects to PUL+, and Pin 7 to DIR+. Connect all of the other pins to GND on the logic side. Connect the VIN/VCC and GND pin on the Arduino and Stepper driver to a 9-12V 1A power supply. Connect the stepper motor to the B-, B+, A-, and A+ of the stepper driver according to the datasheet of your motor. Slide the driver in, and connect the two small pieces.
