ROCK, PAPER, SCISSORS
IT HAS BEEN A LONG HARD ROAD...
Still trying to get the code to work... But i am considering changing route.
//-----------abs values for rock paper scissors
#define rock 2
#define paper 0
#define scissors 1
int inByte= -1; // incoming byte from serial RX
int switchPin1 = 12; // digital input pin for a switch
int switchPin2 = 11;
int switchPin3 = 10;
int yellowLed = 3; // digital output pin for an LED
int redLed = 2;
int greenLed = 9;
int switchState1 = 0; // the state of the switch
int switchState2 = 0; // the state of the switch
int switchState3 = 0; // the state of the switch
int Loc = 0;
int Rem = 0;
int winner = 0;
//________________________________________
void setup() {
//-----------configure serial communications:
Serial.begin (9600);
pinMode(switchPin1, INPUT); // set the switch pin to be an input
pinMode(switchPin2, INPUT); //
pinMode(switchPin3, INPUT); //
pinMode(yellowLed, OUTPUT); // set the yellow LED pin to be an output
pinMode(redLed, OUTPUT); //
pinMode(greenLed, OUTPUT); //
//-----------set XBee's destination address:
setDestination();
//-----------blink the TX LED indicating that the main program's
//about to start:
}
//________________________________________
void setDestination() {
// put the radio in command mode:
Serial.print("+++");
// wait for the radio to respond with "OK\r"
char thisByte = 0;
while (thisByte != '\r') {
if (Serial.available() > 0) {
thisByte = Serial.read();
}
}
// set the destination address, using 16-bit addressing.
// if you're using two radios, one radio's destination
// should be the other radio's MY address, and vice versa:
Serial.print("ATDH0, DL1000\r");
// set my address using 16-bit addressing:
Serial.print("ATMY2000\r");
// set the PAN ID. If you're working in a place where many people
// are using XBees, you should set your own PAN ID distinct
// from other projects.
Serial.print("ATID0911\r");
// put the radio in data mode:
Serial.print("ATCN\r");
}
