Unlike normal DC motors that just spin when connected to a battery, a Stepper Motor is a precision instrument. It doesn't just spin; it rotates in exact, measurable "steps." This is why 3D printers, CNC machines, and robotic arms use them.
To make a stepper motor rotate, the microprocessor must send an electrical pulse to its internal electromagnetic coils in a very specific, sequential pattern. If the software sends the wrong binary code, the magnetic fields fight each other. The motor will violently stutter, vibrate, and eventually burn out.
⚠️ CRITICAL GLITCH: Payload Arm Stutter
The Hardware: The robotic arm's base uses a 4-coil stepper motor (Coils: A, B, C, D). A logic '1' turns a coil ON, a logic '0' turns it OFF.
The Bug: The microprocessor is currently sending this corrupted 4-step sequence:
Step 1: 1000 (Coil A is ON)
Step 2: 0100 (Coil B is ON)
Step 3: 1000 (Coil A is ON again! ERROR!)
Step 4: 0001 (Coil D is ON)
Because the sequence jumps backward, the rotor just shakes in place.
Your Mission: Input the correct 16-bit binary sequence (4 steps of 4 bits) to achieve a smooth "Full-Step" clockwise rotation.
