In order to get complete control of the motor we need to take control of the speed and direction of the motor, and to do that we need to use Pulse Width Modulation or PWM Technique to control the speed and we are going to use the internal H-bridge to control the direction of the motor. Controlling DC motors with Microcontrollers Here we have used Arduino Pro Mini, however any Arduino model can be used to built this project. So, in this project, we will be Interfacing the DRV8833 motor driver IC with Arduino and in the way, we will know all the details about this IC. But there exists another IC named DRV8833 that also provides dual drive motor driver solution and it's cheaper than the L293D IC. The maximum speed for a 28byj-48 stepper motor is roughly 10-15 rpm at 5 V.If you are interested in building robots then it is certain that you need to learn how to control the speed and direction of a DC motor, and in one of our previous tutorials, we did just that using the popular L293D Motor Driver IC and ESP32. In the setup, you can set the speed in rpm with the function setSpeed(rpm). This allows you to easily control 2 or more stepper motors at the same time. You can create multiple stepper motor objects with different names and pins. Stepper liftmotor = Stepper(stepsPerRevolution, 8, 10, 9, 11). In this case I called the stepper motor ‘myStepper’ but you can use other names as well, like ‘z_motor’ or ‘liftmotor’ etc. To get the correct step sequence, we need to set the pins in the following order: 8, 10, 9, 11. For this we use the function Stepper(steps, pin1, pin2, pin3, pin4) where steps is the number of steps per revolution and pin1 through pin4 are the pins to which the motor is connected. Next, you need to create a new instance of the Stepper class, which represents a particular stepper motor connected to the Arduino. This means it takes 2048 steps to rotate 360 degrees (see motor specifications above). In this example we will be using the motor in full-step mode. Next, I defined how many steps the motor takes to rotate 1 revolution. Include the Arduino Stepper.h library: More information about this library can be found on the Arduino website. The sketch starts by including the Stepper.h Arduino library. Step one revolution in the other direction: Begin Serial communication at a baud rate of 9600: Stepper myStepper = Stepper(stepsPerRevolution, 8, 10, 9, 11) Create stepper object called 'myStepper', note the pin order: * Example sketch to control a 28BYJ-48 stepper motor with ULN2003 driver board and Arduino UNO. Although it is not super accurate or powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors. The 28BYJ-48 is one of the cheapest stepper motors you can find.
