serial input mapped to servo?


i have both these sketches , running i'd map sonar servo.


is possible? unfortunately i'm total noob. thank help.


sonar test code: ( i'm reading output on serial )
/*

vcc arduino 5v gnd arduino gnd
echo arduino pin 13 trig arduino pin 12
red pos arduino pin 11
green pos arduino pin 10
560 ohm resistor both led neg , grd power rail

#define trigpin 12
#define echopin 13
#define led 11
#define led2 10

void setup() {
  serial.begin (9600);
  pinmode(trigpin, output);
  pinmode(echopin, input);
  pinmode(led, output);
  pinmode(led2, output);
}

void loop() {
  long duration, distance;
  digitalwrite(trigpin, low);  // added line
  delaymicroseconds(2); // added line
  digitalwrite(trigpin, high);
//  delaymicroseconds(1000); - removed line
  delaymicroseconds(10); // added line
  digitalwrite(trigpin, low);
  duration = pulsein(echopin, high);
  distance = (duration/2) / 29.1;
  if (distance < 4) {  // led on/off happens
    digitalwrite(led,high); // when red condition met, green led should turn off
  digitalwrite(led2,low);
}
  else {
    digitalwrite(led,low);
    digitalwrite(led2,high);
  }
  if (distance >= 200 || distance <= 0){
    serial.println("out of range");
  }
  else {
    serial.print(distance);
    serial.println(" cm");
  }
  delay(500);
}

#include <servo.h>

servo myservo;  // create servo object control servo
// twelve servo objects can created on boards

int pos = 0;    // variable store servo position

void setup() {
  myservo.attach(9);  // attaches servo on pin 9 servo object
}

void loop() {
  (pos = 0; pos <= 180; pos += 1) { // goes 0 degrees 180 degrees
    // in steps of 1 degree
    myservo.write(pos);              // tell servo go position in variable 'pos'
    delay(15);                       // waits 15ms servo reach position
  }
  (pos = 180; pos >= 0; pos -= 1) { // goes 180 degrees 0 degrees
    myservo.write(pos);              // tell servo go position in variable 'pos'
    delay(15);                       // waits 15ms servo reach position
  }
}

please use [ code ] tags next time, "how use forum" shows you.

well, think map() function might useful you. read how works. try map distance (or duration) pos (position).
