In these posts the schematics used. What kind of code would i use for this, and where can i find it?

Are you asking about the schematics package?
Eagle?

2N2222 is Small Signal NPN Transistors and you can get it from your local store or order on-line with digikey or mouser.
No, i was talking about the picture of the schematic, in the link.
In that case, this is what you want:
For the code you can use this for sending
\arduino-0015\examples\Communication\ASCIITable
For Receive you can use this code

SoftwareSerial modify example
Sample of the SoftwareSerial library. Listens for serial in on pin 2
and sends it out again on pin 3.

// include the SoftwareSerial library so you can use its functions:
#include <SoftwareSerial.h>
#define rxPin 2
#define txPin 3
#define ledPin 13
// set up a new serial port
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);
byte pinState = 0;
void setup() {
// define pin modes for tx, rx, led pins:
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
pinMode(ledPin, OUTPUT);
// set the data rate for the SoftwareSerial port
mySerial.begin(9600);
Serial.begin(9600); // Monitor thru USB serial monitor
}
void loop() {
// listen for new serial coming in:
char someChar = mySerial.read();
// print out the character:
mySerial.print(someChar);
Serial.print(someChar, BYTE); // prints value unaltered, first will be '!'
// toggle an LED just so you see the thing's alive.
// this LED will go on with every OTHER character received:
toggle(13);
}
void toggle(int pinNum) {
// set the LED pin using the pinState variable:
digitalWrite(pinNum, pinState);
// if pinState = 0, set it to 1, and vice versa:
pinState = !pinState;
}
I use the same program for both the receiver and the transmitting circuit, right?
Wrong.

o hah i didnot see that haha!
