21. PWM High-Frequency Generation

There is a DC motor that requires a PWM frequency between 5 to 10 kHz to drive it. Low PWM frequency generates noise while driving the motor.

So,

  • Generate a PWM with any frequency between 5 to 10 kHz using a microcontroller.
  • Control the PWM duty cycle using a potentiometer to adjust the motor's speed.

Note: If you don’t have DSO to analyze the output PWM frequency, you can use simulation tools like Proteus, Wokwi, or any other platform.
