Not sure what you mean by 'zero'. You can do a "servo.write(0)' in setup for each of your servos. But that (or manual positioning) does not address the servo variablility issue.
You need to figure out what values will send your servos to 0 and 180 degrees without hitting the stops. You can then use the 'map()
' function to scale 0-180 to the right values for your servo.
got it! thank you so much. kind of wish i would have got the 360 servos but this will be good for us.
i looked at the bulk ordering for schools. id like to get at least 10 360 servos for our students along with 10 arduinos, 10 protshields led and wires .
Anyway . I'm putting together a wish list.
