 * Included in study group kit
 * Red = 5V
 * Brn = Gnd
 * Orange = signal input Pin 10 on this demo
 * 
 * PURPOSE: 
 *  DEMO HOW TO SET SG-90 SERVO POSITION WITH SERIAL MONITOR
 *  Shows how to use serial monitor for intput
 *  
 *  commands: 1500 = center
 *            1000 = full left
 *            2000 = full right
 *            try using 900-1000 and 2000-2500 to set precise angle
