Web9 Mar 2024 · Output B duty cycle: (50+1) / 256 = 19.9%. The output frequency is the 16MHz system clock frequency, divided by the prescaler value (64), divided by the 256 cycles it … WebHobby servo motors can be controlled using PWM. They require a frequency of 50Hz and then a duty between about 40 and 115, with 77 being the centre value. If you connect a servo to the power and ground pins, and then the signal line to pin 12 (other pins will work just as well), you can control the motor using:
