A Test bank is a ready-made electronic testing resource that can be customized by lecturers for their teaching. Novak's heavy-duty ESC and motors can handle the harshest of conditions and the heaviest rigs and are ideal for 4x4 and 2WD SCT.
The following schematic shows the different blocks in a circuit to drive a unipolar stepper motor.
Motor Driver circuit and Unipolar Stepper Motor - the Motor Driver circuit translate the QA and QB digital signals to appropriate drive currents required by the stepper motor.

To prevent false alarms produced by a single sensor activation, the alarm will be triggered only when at least two sensors activate simultaneously. Once we receive your payment we will send your files immediately by email attachment or download link. Sensor-based electronics allow for optimal performance whether you are hardcore racing or hardcore bashing.
D will determine the direction of rotation and the CLK frequency will set the rotation speed.
The ULN2003, a high voltage, high current darlington driver comprising seven NPN darlington pairs, is used to drive the motor.

If you run the stepping sequence forward, the stepper rotates clockwise; run it backward, and the stepper rotates counterclockwise. The ULN2003 has a maximum sustaining output voltage of 50V and maximum output current of 0.5A per channel which easily meet the requirements of the Mycom PF443 stepper motor.
