Finally, connect the A (Red), A- (Green), B (Blue) and B- (Yellow) wires from the stepper motor to the L293Ds output pins (Out4, Out3, Out2 Out1) as shown in the illustration below.

It can control both speed and spinning direction of any Unipolar stepper motor like 28BYJ-48 or Bipolar stepper motor like NEMA 17. If you want to learn the basics of L293D IC, below tutorial is invaluable. Consider reading (at least skimming) through this tutorial first. Control DC Motors with L293D Motor Driver IC Arduino If you are planning on assembling your new robot friend, you will eventually want to learn about controlling DC motors. Controlling a Stepper Motor With an H-Bridge As L293D IC has two H-Bridges, each H-Bridge will drive one of the electromagnetic coils of a stepper motor. By energizing these electromagnetic coils in a specific sequence, the shaft of a stepper can be moved forward or backward precisely in small steps. However, the speed of a motor is determined by the how frequently these coils are energized. Driving Unipolar Stepper Motor (28BYJ-48) In our first experiment, we are using 28BYJ-48 unipolar stepper rated at 5V. Before we start hooking the motor up with the chip, you will need to determine the A, A-, B and B- wires on the motor you plan to use. ![]() Note that we will not be using the common center connection(Red) in this experiment. The center connection is merely used to energize either the left or right side of the coil, and get the effect of reversing the current flow without having to use a circuit that can reverse the current. Start by connecting 5V output on Arduino to the Vcc2 Vcc1 pins. You also need to connect both the ENA ENB pins to 5V output so the the motor is always enabled. Now, connect the input pins(IN1, IN2, IN3 and IN4) of the L293D IC to four digital output pins(12, 11, 10 and 9) on Arduino. Finally, connect the stepper motors wires A (Orange), A- (Pink), B- (Yellow) and B (Blue) to the L293Ds output pins (Out4, Out3, Out2 Out1) as shown in the illustration below. Wiring L293D Motor Driver IC to 28BYJ-48 Stepper Motor Arduino Driving Bipolar Stepper Motor (NEMA 17) In our next experiment, we are using NEMA 17 bipolar stepper rated at 12V. It offers 200 steps per revolution, and can operate at 60 RPM. Start by connecting external 12V power supply to the Vcc2 pin and 5V output on Arduino to the Vcc1 pin.
