+/**
+ * ServoRamp
+ *
+ * Use ramps to move the position of a RC servo motor with your Arduino and a potentiometer.
+ * 
+ * Circuit:
+ *
+ * Servo motors have three wires: power, ground, and signal. The power wire is
+ * typically red, and should be connected to the 5V pin on the Arduino or Genuino
+ * board. The ground wire is typically black or brown and should be connected to
+ * a ground pin on the board. The signal pin is typically yellow, orange or white
+ * and should be connected to pin 9 on the board.
+ *
+ * Note that servos draw considerable power, so if you need to drive more than
+ * one or two, you'll probably need to power them from a separate supply (i.e. not
+ * the +5V pin on your Arduino). Be sure to connect the grounds of the Arduino and
+ * external power supply together.
+ *
+ * Created in 2025 by Sofian Audry
+ *
+ * Inspired from the following code:
+ * https://www.arduino.cc/en/Tutorial/Knob
+ * https://www.arduino.cc/en/Tutorial/Sweep
