serial monitor gibberish

Using Arduino Programming Questions
#1

When I run the attached program the monitor prints gibberish (as shown at the bottom of the program).
The program did run correctly prior to installing a bluetooth module (which was disconnected for this demo).
Thanks for any help.

// Servo_angle-Ping_1

#include <Servo.h>
#include <NewPing.h>

#define TRIGGER_PIN 12
#define ECHO_PIN 11
#define MAX_DISTANCE 200

NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE);

Servo myservo;

int n = 0; // variable to store servo position

String readString;
void setup()
{
myservo.attach(5); // attaches servo on pin 5
myservo.write(90);
delay(200);

// initalize the serial communication:
Serial.begin(57600);
Serial.flush();
Serial.println(“Servo Angle”);
}
void loop()
{
for(n = 45; n < 135; n += 1)
{
Serial.println(n);
myservo.write(n);
delay(100);
unsigned int uS = sonar.ping();
Serial.print("Ping: ");
Serial.print(uS / US_ROUNDTRIP_CM);
Serial.println(“cm”);
}

for(n = 135; n >= 45; n -= 1)
{
Serial.println(n);
myservo.write(n);
delay(100);
unsigned int uS = sonar.ping();
Serial.print("Ping: ");
Serial.print(uS / US_ROUNDTRIP_CM);
Serial.println(“cm”);
}

}

monitor displays:

Have you confirmed the serial terminal baud rate is the same as your sketch?

#3 
  Serial.begin(57600);
  Serial.flush();
  Serial.println("Servo Angle");

You don't even get the print from within the setup() ?
I would start there. slow down the speed, put in a couple of delays. You should be able to get a serial print from within the setup(). If you have other hardware attached, maybe disconnect them for test.

Weedpharma,
That solved it, terminal baud rate was not the same as the sketch!
Thank you, thank you!
