serial controlling a servo?

Here is a test program I wrote (I think I modified an existing sketch I don't remember) that does what you want.  To use it send

1S0# - 1S180# to position the servo from 0 to 180 degrees.

// Test program for the SG-90 servo motor

//

#include <Servo.h>

#define SerialSpeed 9600

#define BufferLength 16

#define LineEnd '#'

#define PinServo1 5

#define DefaultPosition 90

Servo servo1 ;

char inputBuffer[BufferLength] ;

void setup()

{

   pinMode(PinServo1, OUTPUT) ;

   // Attach servo and set servo min/max timing, and move to default position

//   servo1.attach(PinServo1, 560, 2420) ;

   servo1.attach(PinServo1) ;

   servo1.write(DefaultPosition) ;

   Serial.begin(SerialSpeed) ;

}

void HandleCommand( char *input, int length)

{

    Serial.println(input) ;

    if (length < 2)

      {

        return ; // Invalid command length

      }

    int value = 0 ;

    if (length > 2)

      {

        value = atoi(&input[2]) ;

        if ((value < 0) || (value > 180))

          {

            return ; // Invalid position parameter

          }

      }

    int *command = (int *)input ;

    switch (*command)

      {

        case '1S':

          servo1.write(value) ;

          break ;

        default:

          Serial.println("Unknown command") ;

          break ;

      }

}

void loop()

{

  // Get a command stringfrom the serial port

   int inputLength = 0 ;

   do {

        while (!Serial.available()) ; // Wait for command

        inputBuffer[inputLength] = Serial.read() ;

      } while ((inputBuffer[inputLength] != LineEnd) && (++inputLength < BufferLength)) ;

    inputBuffer[inputLength] = 0 ; // Make sure command string is null terminated

    HandleCommand(inputBuffer, inputLength) ;

}

I am assuming this test code works, it seems to have all the basics you need to control the servo, you simply need to modify it and the commands to be able to work with two servos.

not meaning to imply anything but do you understand what this code is doing (The code you just provided, not the code in the original post), just if you do understand it then I fail to understand how you came up with your first code sample as it is so much closer to what you would need

please add a schematic showing how you see this all being connected including how you intend to control it

also what do you mean by "i don't feel like changing the variables and re uploading the code to my arduino uno" ?

just realised this was from someone else Helping Kyle, Sorry Gary

Like I said, this one looks like it should do the trick so Kyle, try to understand the one Gary provided and go from there

Again, Sorry Gary.
