I want to combine these two programs, how can i make it successful.

#include <SoftwareSerial.h> // TX RX software library for bluetooth

#include <Servo.h> // servo library
Servo myservo; // servo name

int bluetoothTx = 10; // bluetooth tx to 10 pin
int bluetoothRx = 11; // bluetooth rx to 11 pin

SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);

void setup()
{
myservo.attach(9); // attach servo signal wire to pin 9
//Setup usb serial connection to computer
Serial.begin(9600);

//Setup Bluetooth serial connection to android
bluetooth.begin(9600);
}

void loop()
{
//Read from bluetooth and write to usb serial
if(bluetooth.available()> 0 ) // receive number from bluetooth
{
int servopos = bluetooth.read(); // save the received number to servopos
Serial.println(servopos); // serial print servopos current number received from bluetooth
myservo.write(servopos); // roate the servo the angle received from the android app
}

}
#include <Servo.h>

Servo Mservo; // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 90; // variable to store the servo position
void setup() {
Mservo.attach(6); // attaches the servo on pin 6 to the servo object
}

void loop() {
for (pos = 90; pos <= 180; pos += 5) { // goes from 90 degrees to 180 degrees
// in steps of 1 degree
Mservo.write(pos); // tell servo to go to position in variable 'pos'
delay(10); // waits 10ms for the servo to reach the position
}
for (pos = 180; pos >= 90; pos -= 1) { // goes from 180 degrees to 90 degrees
Mservo.write(pos); // tell servo to go to position in variable 'pos'
delay(10); // waits 10ms for the servo to reach the position
}
}

here i mixed two codes in the same program,the 1st one is to control a servo through bluetooth and the 2nd one is to control a servo to move from 90 -180 degrees with a switch,after this i got an error "exit one redefinition of 'void setup()' ".Can anyone help me in this problem.

Any Arduino sketch can have only one setup() and one loop() function. Here and here are pages about combining sketches. You may run into trouble using software serial and servo libraries together. A forum search for "servo and software serial" will yield pages with possible solutions.

And apart from what groundfungus said, I think you'll have other problems reading the bt because of the blocking nature of the "for" loops doing your sweeps.
