4 Wire Stepper Motor Arduino Code

The define steps 100 line defines the number of steps per rev.
4 wire stepper motor arduino code. Also i include arduino code to drive the 28byj 48 stepper motor without installing any additional libraries. This shows you how to use a cheap 4 pin stepper motor bought from china link to the code. You can find the other interface types here. To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11.
The circuit diagram for the arduino stepper motor control project is shown above. You can find the other interface types here. In this case we will be driving a 4 wire stepper motor in half step mode so we set the interface type to 8. We get familiar with the specifications and the wire connections for driving the stepper motor from an arduino microcontroller.
Basic arduino example code to control a 28byj 48 stepper motor. The shaft of a stepper motor rotates in discrete steps. The example code assumes that the stepper is being controlled by arduino pins 8 9 10 and 11 but you can use any set of four pins. Stepper motor control using arduino is a simple project where a bipolar stepper motor is controlled using arduino uno.
The motor interface type must be set to 4 when using a 4 wire stepper motor in full step mode 200 steps revolution. As shown in the fritzing diagram an external power source can be connected to power the motors. This was an old stepper motor that i pulled out my junk pile i m not sure what it came from i think it was an old printer from the 80s. For a stepper motor the 4 terminal pins on the h bridge should connect to the 4 leads of the motor.
Stepper h library example code for l298n driver with stepper motor and arduino. We have used the 28byj 48 stepper motor and the uln2003 driver module. If you want to run the motor in full step mode fewer steps per revolution just change the 8 to 4. The 4 logic pins will then connect to the arduino 8 9 10 and 11 in this tutorial.
Arduino stepper motor control circuit diagram and explanation. This is a remake of a earlier video. Here we look at the 28byj 48 stepper motor with the uln2003 driver. Arduino 6 wire stepper motor tutorial.
