 ************************************************ Important stuff if needed ****************************************
 *
 * You need both a servo motor and a power supply correct for that servo motor! Best to use an external battery
 * even if you have a 3.3 V Servo motor.
 *
 *
 * MUST HAVE A 6 VOLT EXTERNAL BATTERY
 * Note: REMEMBER 2 WIRES GO TO THE SERVO GROUND (Battery Neg and Board GND)
 * Servos run from 0 to 180 degrees, test 20 - 160 first
 * 
 * servo red to 6V battery positive
 * servo ground (brown or black) to 6V battery negative
 * servo ground (brown or black) to board GND
 * servo controller (orange or the other color) to board PWM pin D2   
 * 
 * Note For PWM pins check your boards Pinout diagram.
 * For platform.io you need this line in your platform.ini file at the bottom of the file
 lib_deps = arduino-libraries/Servo
