1. How does PWM control H-Bridge?
- The PWM signal controls how fast the motor turns, and the H-bridge acts as a switch, turning the supply voltage on or off based on the PWM signal.
2. How does a stepper motor work with PWM?
- PWM (Pulse Width Modulation) involves rapidly switching the output voltage to the motor on and off. This applies a very high voltage to the motor's coils (typically eight times the motor's nominal voltage), causing the current to rise quickly and be higher than it would be otherwise.
