use pin 0 (RX) and 1 (TX) for wireless connection

Hi!

I tried it with connecting RX and TX with a jumper cable.

LED is blinking when it receives data.

int send = 5;
int income = 0;
int led = 12;

void setup() {
pinMode(led, OUTPUT);
Serial.begin(9600);
}

void loop(){

// transmitter
Serial.print("I sent: ");
Serial.println(send, DEC);

// reciever
if (Serial.available()) {
digitalWrite(led, HIGH); // sets the LED on
delay(1000); // waits for a second
digitalWrite(led, LOW); // sets the LED off
delay(1000);

income = Serial.read();
Serial.print("I received: ");
Serial.println(income, DEC);
}
delay(2000);
}

But the output is quiet strange:

I sent: 5
I received: 32
I sent: 5
I received: 115
I sent: 5
I received: 101
I sent: 5
I received: 110

The value of "I received" should be 5, I assume!?

Thanks for help!!
