hey guys, i need some help to connect my two aurdino's, i am thinking of a bluetooth connection.
i'm sensing temperature using lm35 and currently uploaded the data to one aurdino. Now i have to send the data to another aurdino using bluetooth and i have no idea how to. please help me with the code and interfacing. Thanks , any help would be appreciated.
nt val;
int tempPin = 1;

void setup()
{
Serial.begin(9600);
}
void loop()
{
val = analogRead(tempPin);
float mv = ( val/1024.0)5000;
float cel = mv/10;
float farh = (cel9)/5 + 32;

Serial.print("TEMPRATURE = ");
Serial.print(cel);
Serial.print("*C");
Serial.println();
delay(1000);

/* uncomment this to get temperature in farenhite
Serial.print("TEMPRATURE = ");
Serial.print(farh);
Serial.print("*F");
Serial.println();

*/
}
PS. this is the code i used to sense temperature.

Which distance?

Anyway, your options are

wired:
short distance (50cm or so): directly connected software serial, I2C, SPI
longer (15 meters): software serial with RS232 drivers
much longer (to 1000 plus meters): software serial with RS422 or RS485

wireless:
433MHz, wifi, bluetooth, nrf24 (no real expertise with any of those).

School assignment?

Bluetooth is like serial-by-wireless. When you have your connection established the examples in Serial Input Basics may be useful. The technique in the 3rd example will be most reliable.
