  Suggested limits. A person must confirm every limit before this device can be written.
  The sketch is the ServoArm example of the OpenHAL Arduino library, with the servo on pin 3 of an Arduino
  Uno or pin 13 of an ESP32. The board allows 20 to 160 degrees at 90 degrees per second and returns to 90
  degrees when heartbeats stop for 3 s. This file keeps the arm between 30 and 150 degrees at half that speed.
  Check that nothing is in reach of the arm at either end before you confirm.
