servo software

[scrubs]

I just got an Arduino and am trying to turn a servo.  The problem is i can't get the servo to turn 90 degrees at once.  With the sample code
from www.arduino.cc (plus some slight modifications) I can still only get my servo to turn about 10 degree steps.  Here is my code:

int servo = 9;
int angle;
int pulseWidth;

void servoPulse(int servo, int angle){
  pulseWidth = (angle * 35);
  digitalWrite(servo,HIGH);
  delayMicroseconds(pulseWidth);
  digitalWrite(servo,LOW);
  delay(20);
}
void setup(){
  pinMode(servo,OUTPUT);
  Serial.begin(9600);
}
void loop(){
  angle = Serial.read();
  angle -= 48;
  Serial.println(angle);
  servoPulse(servo,angle);
  delay(1000);
}

I don't see anything wrong in the code, but im new to robotics so if you see anything pleas say something.

thanks in advance

What do you mean by 10 degree steps? 0, 10, 20?

if you look at this code:
pulseWidth = (angle * 35);
and lower 35 to something smaller, you can get better resolution

(I think thats what you meant?)
