STEPPER MOTOR WORKING PRINCIPLE: This explains the working principle of a stepper motor, which rotates in fixed angular steps by sequentially energizing stator windings. The rotor, a permanent magnet, aligns itself with the active stator poles based on the input pulse sequence. In the top illustration, the coil activation pattern follows a specific order, resulting in clockwise rotation. Reversing the sequence, as shown in the bottom image, causes counterclockwise rotation. The truth table along

Control Stepper Motors with Arduino: Beginner's Guide Curious about how to control a stepper motor with Arduino? In this beginner-friendly Arduino tutorial, I'll guide you through the entire process of connecting your stepper motor to an Arduino Uno and coding an Arduino sketch that controls direction and speed.
