I know this is an old post, but I have the same question as the OP. Admin, you say "Have your 168 run this code below. Before modifying your servo, run the code and modify '30' until the servo centers. Then modify the servo and turn the pot until the servo doesn't rotate."
Maybe I don't understand how the servo functions because I haven't built the circuit and powered it up yet. So I run the code and adjust the value until the servo centers, but is something still moving at this point? Because then you say modify the servo and turn the pot until it doesn't rotate. Is it still moving after it centers? Any clarification would be appreciated.
