Inside the setup() function, I set the speed to 100, activated the serial communication and selected 9600 as the baud rate. I defined, two variables vrx_data and vry_data of the type integer for storing the values coming from the Joystick.Īs you know the type of the Joystick I am using also comes with a Pushbutton, I connected the Joystick pushbutton with the Arduino’s pin number 4, defined some flags state, and switch_flage. The VRx and VRy pins of the 2-axis Joystick are connected with the Arduino’s analog pins A0 and A1

If ( (vrx_data >= 0) & (vrx_data 20) & (vrx_data < 490) )ĬD ROM Stepper Motor Arduino Code Explanation:Īs usual, i started off by adding the Stepper.h header file.ĭefined two pins 6 and 7 for the ENA and ENB pins of the motor controller shield. Serial.println("Stepper motor is ActivE") Serial.println("Stepper motor is not active")

Now let’s have a look at the pinout of the L298N Motor Driver.ĬD ROM Stepper Motor Arduino Programming:īefore, you start the programming, first of all, make sure you download the Stepper library. Let me tell you once again if you are using stepper motors with current ratings greater than 4amps then never use the l298N motor driver. The VCC pin of the joystick is connected with the Arduino’s pin number 5, while the ground is connected with the Arduino’s Ground.
The Switch is connected with the Arduino’s pin number 4. The VRx and VRy pins of the joystick are connected with the analog pins A0 and A1. J1 is the DC female power jack, this is where we connect the external 12v or 5v power supply and finally connect the VCC of the L298N motor driver with the Arduino’s 5volts. The enables pins of the l298n motor driver by default comes with the jumper caps, so make sure you remove the jumper caps and connect the enable pins with the Arduino’s pin number 6 and pin number 7. While the input pins of the l298N motor driver are connected with Arduino’s Pin number 8, 9, 10 and 11. So the Unipolar stepper motor connection with the l298n motor driver is exactly the same as the bipolar stepper motor.Īs you can see in the circuit diagram the four wires of the stepper motor are connected with the out1, out2, out3, and out4. Well, the common wires are not connected. You might be thinking what about the Unipolar motors as they have 6 wires.
The L298N motor driver is basically designed for controlling simple dc motors in my previous tutorials, I used this motor driver for controlling the Robot.Īs the L298N motor driver has the ability to control 2 dc motors at the same, and as you know a stepper motor has 4 wires, so it means we can use the L298N motor driver to control a Unipolar or bipolar stepper motor. As the stepper motor, I am using has current requirement less than 4amps so that’s why I decided to use the L298N motor driver. The circuit diagram as you can see on the screen will remain the same for all types of the stepper motors. Regardless of the type and size of the stepper motor the basic working principle of all the stepper motors is exactly the same. I would appreciate your support in this way!ĬD ROM Stepper Motor with Arduino Circuit Diagram: I may make a commission if you buy the components through these links.

In these tutorials, I have explained how to control the Stepper motors using the CNC shield, and how to control Stepper Motors using the IoT “internet of things” technology. Recently I posted new articles on bipolar steppers motors. Stepper motors are used worldwide in industries, robots, toys, printers, CNC machines, 3D printers, etc. UniPolar and Bipolar Stepper Motors Basics: So I highly recommend first you should watch these tutorials and then you can resume from here. The same program and circuit connections can be used for the other types of stepper motors.įor the extreme basics, you can watch my getting started tutorials on the bipolar and unipolar stepper motors, 2 Axis Joystick and L298n motor driver. The stepper motor control system can be activated and deactivated using the joystick push button. In this tutorial, you will learn how to control the speed and direction of the CD ROM stepper motor using 2 axis joystick, L298N motor driver, and Arduino.
