+/* * --------------------------------------------------------------------------
+ * writeMicroseconds_Example 
+ * --------------------------------------------------------------------------
+ * The writeMicroseconds() function is part of the Servo Library.
+ * It sets the servo's angle by accepting a pulse width duration measured in microseconds (µs).
+ * * CORE TIMING VALUES (Note: Values can vary slightly by servo model):
+ * * 1. Minimum Position (0 degrees):
+ * - Value: 544 microseconds (us)
+ * - Result: Servo moves to its extreme counter-clockwise limit (0°).
+ * * 2. Center Position (90 degrees):
+ * - Value: 1500 microseconds (us)
+ * - Result: Servo moves to its neutral, center position (90°).
+ * * 3. Maximum Position (180 degrees):
+ * - Value: 2400 microseconds (us)
+ * - Result: Servo moves to its extreme clockwise limit (180°).
+ *
+ * * BASIC WORKING PRINCIPLE:
+ * Servo motors use Pulse Width Modulation (PWM). The duration (width) that the
+ * control wave is held HIGH directly determines the commanded angle. This function
+ * allows for precise, non-standard movement by letting the user specify the exact time duration.
