Control the motion of a servo using the Serial Monitor.

A "servo", short for servomotor, is a motor that includes feedback circuitry that allows it to be commanded to move to specific positions. This one is very small, but larger servos are used extensively in robotics to control mechanical arms, hands, etc. You could use it to make a (tiny) robot arm, aircraft control surface, or anywhere something needs to be moved to specific positions. ####Hardware connections: The servo has a cable attached to it with three wires. Because the cable ends in a socket, you can use jumper wires to connect between the Arduino and the servo. Just plug the jumper wires directly into the socket. Connect the RED wire (power) to 5 Volts (5V) Connect the WHITE wire (signal) to digital pin 9 Connect the BLACK wire (ground) to ground (GND) Note that servos can use a lot of power, which can cause your Arduino to reset or behave erratically. If you're using large servos or many of them, it's best to provide them with their own separate 5V supply. See this Arduino Forum thread for info: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1239464763 * After uploading this code to your Arduino, open up the serial monitor and type in an angle from 0 to 180 to set / control the Servo Motor. ####Wiring Diagram
