Design PWM-based control of motors and actuators from a microcontroller, covering PWM generation, H-bridge and driver interfacing, closed-loop control with feedback, and protection.
## CONTEXT Driving a motor or actuator from a microcontroller is where firmware meets the physical world with real power and real consequences, and getting it wrong burns out drivers, browns out the supply, or makes the system unstable. PWM is the foundation: by switching power on and off rapidly and varying the duty…
