Mini Linear Actuator Using 28BYJ-48 5V Stepper: A Cost-Effective Solution A modified 28BYJ-48 stepper is utilized to achieve increased torque, thanks to a clever bipolar hack. To access this modification, remove the blue motor cover and carefully cut the center trace, then locate and eliminate the red wire. For detailed information on this process, search for "28BYJ-48 bipolar hack" online. A simple momentary pushbutton is used to control direction in the test setup, demonstrating a straightforward implementation of basic motor control. Affordable components such as the Arduino Nano microcontroller and 28BYJ-48 stepper motor can be sourced for under $10 each. However, when powering up both the A4988 motor controller and the Arduino Nano from different sources (USB and motor), ensure that the link is removed to avoid any potential issues. As a beginner programmer, this project showcases a working solution with the assistance of "The Dronebot Workshop". It's essential to connect the stepper motor before powering up the A4988 motor controller.
