/*
 * This Sketch was created by GR3Y, feel free to modify in anyway.
 * 
 * This Sketch is used with the laserturret or any following turret projects.
 * 
 * Controls servos on pins 4 and 5 with angles specified by data in from serial.
 * 
 * Simple explanation, the wiper of first pot is put on digital pin 4, same for the second pot (both pots are 10K) the other pins on the pot are either put to ground (-) or VCC (5V).
 * 
 * If an axis is reversed then make swap the 0 value infront of 180 in ValX or valY a negative E.G  
 *
 *  valX = map(valX, 0, 1023, 0, 180); if x axis is inverted then swap the 0 value with 180
 *
 *  valX = map(valX, 0, 1023, 180, 0);
