public abstract class ServoFinderOpMode extends FinderOpMode
Finds a servo's numbers: its safe ends (limits) and the positions you want (open, closed, ...). Nudge the servo with the D-pad, mark the ends and positions, and copy the code lines it shows. No code to write: it lists every servo in the robot configuration.

It shows the code for PositionServo and, for the robot in five files, the line for Tunables.java: Tunables.Claw: P1 = 0.210, P2 = 0.770 (rename P1, P2 to open, closed). 

 Choose:  D-pad up/down = servo, A = use it, Y = full range on/off (500-2500 us instead of the
          SDK's normal 600-2400: a goBILDA 2000 servo turns 300 degrees instead of 270; use it when
          the part has .fullRange() in Robot.java, so the numbers fit)
 Start:   D-pad = choose a start point (the servo does NOT move yet), A = move it there.
          Pick a value near where it sits now: a servo cannot tell where it is.
 Nudge:   D-pad right/left = +/- 0.01   D-pad up/down = +/- 0.05   hold RB = 10 times finer
          X = mark this as one END, B = mark the other END (where it just stops touching the frame).
          Once both are marked, it stays between them (hold LB to go past, e.g. to mark again)
          A = save this as a position (P1, P2, ...; rename them in your code), Y = undo the last one
          BACK = choose another servo
 Help: GUIDE (or hold START 1 s) = a help page with every button; everything pauses.
The servo does not move until you press A at the start point (its real position is unknown). In your TeamCode: @TeleOp(name = "Servo Finder", group = "Finders") public class ServoFinder extends ServoFinderOpMode { } Docs: docs/modules/finders.md. Guide: docs/guides/finders.md
