Use when driving a 28BYJ-48 stepper via ULN2003, or generating sound from passive/active buzzers on Arduino, ESP32, or Raspberry Pi Pico. Provides exact half-step sequences, step math (2048 steps/rev), RPM/torque limits, holding-current thermal data, coil de-energizing, passive-vs-active buzzer identification, tone() timer conflicts, MicroPython PWM beep patterns, and RTTTL melody playback.
