Stepper Motors Drivers with ULN2003

The integrated circuit ULN2003 can be used as a motor driver for unipolar stepper motors (5 and 6 wires). The videos under Test present circuit implementations with ULN2003 and Arduino Uno or PIC16f877A.

Using 4 ULN2003 and a PIC16F877A I created a Perfboard prototype for multiple applications. An Arduino Uno communicates with the perfboard to change the configurations using I2C/Serial communication.

Since the ULN2003 can be used for multiple applications, and the configuration of the board can be changed, in the following test the Perfboard controls a solenoid. This test proves the wide range of possibilities of the design.
