AVR®: Using PWM to Dim an LED

 In this video:

  • Introduce Pulse Width Modulation (PWM) and the importance of high frequency and resolution.
  • Set a prescaler of 1 to get maximum PWM frequency.
  • Set up two output compare IRQ’s: one to control the period, the other to control the duty cycle.
