So here are all 3 prongs of the plane code thus far. This sends data to the visual basic program, then to the visual basic program where it gets interpreted and then sent to the plane simulator Arduino. Where it is written to servos and and led.

Arduino Controller:

//Mux control pins</pre>
int s0 = 8;
int s1 = 9;
int s2 = 10;
int s3 = 11;

//Shift Register Pins
int SER_Pin = 5; //pin 14 on the 75HC595
int RCLK_Pin = 6; //pin 12 on the 75HC595
int SRCLK_Pin = 7; //pin 11 on the 75HC595
#define number_of_74hc595s 1 //How many of the shift registers - change this
#define numOfRegisterPins number_of_74hc595s * 8 //do not touch
boolean registers[numOfRegisterPins];

//other pin setup
