How does a servo work (PWM or PPM)?

Hi Lefty,

I think there is a good case for keeping the name analogWrite even though pwmWrite would be more technically correct.

Arduino is primarily aimed at non technical users – people that want to do things with Arduino but are not engineers and are much more interested in the ends than the means.

For tasks like varying the intensity of an LED or moving the pointer of an analog meter, a function named analogWrite is more expressive than the more technically correct term.
