Example 2: Joystick controls pan-tilt servos, laser, Rotary Pot controls DC motor speed.

/* YourDuino Example: Servo Joystick Position, DC Motor Speed Control
 - Moves two Servomotors (usually on a pan-tilt kit)
   through a range of positions in response to the position
   of a joystick attached to 2 Analog inputs. Turns Laser ON-OFF
 - Controls speed of a DC motor with a rotary Potentiometer and Power FET
 - SEE the comments after "//" on each line below
 - CONNECTIONS:
 - Joystick connected to +5, Gnd, YourDuino Analog inputs A1 and A2
 - Rotary Potentiometer connected +5, Gnd,  Analog input A0
 - Servo connectors plugged on YourDuinoRobo1 port 3 and 5
   - If separate wires:
   - Servo Black to Gnd.
   - Servo Red or Orange (Center wire) to +5V
   - Servo White or Yellow to Signal (Pin 9 or 10)
