INTERLEAVE – Alternate between single and double to create a half-step in between.

DOUBLE – Two coils are energized at a time for more torque.

SINGLE – One coil is energized at a time.

The direction can be FORWARD or BACKWARD, and the stepstyle can be any of the following: #steps is the number of steps you want it to take.

step(#steps, direction, steptype) function is called every time you want the motor to move.

setSpeed(rpm) sets the motor’s speed, where rpm is the number of revolutions per minute you want the stepper to turn.

Here, you must specify the motor’s steps-per-revolution and the port number to which the motor is connected.

The second line AF_Stepper motor(48, 2) creates a library object. #include // Number of steps per output rotation // Change this as per your motor's specification const int stepsPerRevolution = 48 So, connect an external 5V power supply to the EXT_PWR terminal.įinally, connect the motor to the stepper motor terminals M1-M2 (port #1) or M3-M4 (port #2). Wiring for the 28BYJ-48 unipolar stepperĢ8BYJ-48 unipolar stepper motors are rated at 5V and provide 48 steps per revolution. Begin by mounting the motor shield on top of an Arduino. Our next experiment will involve connecting a stepper motor to the L293D shield. Because the motor shield lacks dynamic braking, the motor may take some time to stop spinning.Įxperiment 2 – Driving Stepper Motors with L293D Shield RELEASE – This stops the motor and is equivalent to setSpeed(0).run(cmd) function controls the motor’s spinning direction.In the program, you can change the speed whenever you want.

The speed ranges from 0 to 255, with 0 being off and 255 being full throttle.

setSpeed(speed) function controls the motor’s speed.

In the setup and loop sections of the code, we simply call the two functions listed below to control the speed and direction of a motor.

The following code snippet, for example, creates two AFmotor objects. If you want to connect multiple motors to the shield, make a separate object for each motor. Write 1 for port M1, 2 for port M2, and so on. Here, you must specify the motor port number to which the motor is connected. The second line AF_DCMotor motor(motorPort#) creates a library object. The sketch begins by including the AFMotor.h library. Decelerate from maximum speed to zero for (i= 255 i!= 0 i-) Accelerate from zero to maximum speed for (i= 0 i< 255 i++)

To install the library, navigate to Sketch > Include Library > Manage Libraries… Wait for the Library Manager to download the libraries index and update the list of installed libraries. This will let us control DC, stepper, and servo motors with simple commands. To communicate with the shield, we must first install the AFMotor.h library.

Please note that the shield does not use the D2 or D13 pins. D10 is connected to Servo 1, while D9 is connected to Servo 2. Arduino to Shield Pin Connectionsįor DC and stepper motor control, the shield makes use of pins D3, D4, D5, D6, D7, D8, D11, and D12.ĭ9 and D10 are used to control the servo motors. You can populate these with headers, making them useful for connecting various sensors. Six analog pins (A0 to A5), as well as 5V and ground connections, are provided in the bottom right corner. It has been brought to the top for easy access. The RESET button is nothing but Arduino’s reset button. The motors will not run if it is not lit. The on-board LED indicates that the motor power supply is working properly. The shield includes a pulldown resistor array to keep motors off during power-up.
