Xtian's Physical Computing

Well with some help from Ben Chao in our code we actually have the Multiplexer being recognized by the Arduino. We hooked up 4 switches and wrote a simple If statement to if 2 switches were pushed a LED would light up. Here is our Code for now:

//************VARIABLES****************
int input = 12; // DIGITAL INPUT TO THE MUX
int d= 5; // SELECT PIN D GOING INTO PIN 5
int c= 4; // SELECT PIN C GOING INTO PIN 4
int b= 3; // SELECT PIN B GOING INTO PIN 3
int a= 2; // SELECT PIN A GOING INTO PIN 2
int pin9 = 9; // OUTPUT FOR THE RED LED INTO PIN 9
int pin8 = 8; // OUTPUT FOR THE WHITE LED INTO PIN 8
int pin10 = 10; // OUTPUT FOR THE GREEN LED INTO PIN 10
int pin11 = 11; // OUTPUT FOR THE YELLOW LED INTO PIN 11
int time;

//***********ARRAY TO STORE THE VALUES FROM THE MUX*********************
int val[] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
//************DIGITAL VALUES TO CONTROL OUR 16 INPUTS*******************
int d_bin[]={LOW,LOW,LOW,LOW,LOW,LOW,LOW,LOW,HIGH,HIGH,HIGH,HIGH,HIGH,HIGH,HIGH,HIGH};
int c_bin[]={LOW,LOW,LOW,LOW,HIGH,HIGH,HIGH,HIGH,LOW,LOW,LOW,LOW,HIGH,HIGH,HIGH,HIGH};
int b_bin[]={LOW,LOW,HIGH,HIGH,LOW,LOW,HIGH,HIGH,LOW,LOW,HIGH,HIGH,LOW,LOW,HIGH,HIGH};
int a_bin[]={LOW,HIGH,LOW,HIGH,LOW,HIGH,LOW,HIGH,LOW,HIGH,LOW,HIGH,LOW,HIGH,LOW,HIGH};

//aux
int close=0;
int open=0;
int a_val=0;
int b_val=0;
int c_val=0;
int d_val=0;

//**************OPENS SERIAL***************
