Why my servo doesn't work?

Projects Programming

Hello!
I built a basic circuit with Arduino and micro servo but when I uploaded this bare program:

Servo myServo;  

void setup() 
{ 
  myServo.attach(9);   
} 
 
void loop() 
{ 
  myServo.write(130);                 
  delay(500);                           
  myServo.write(0);
  delay(500);
}

a heap of compline errors appeared like this ones:

/Users/Standa/Documents/Arduino/libraries/Servo/Servo.cpp: In member function 'uint8_t Servo::attach(int)':
/Users/Standa/Documents/Arduino/libraries/Servo/Servo.cpp:28: error: 'digitalWrite' was not declared in this scope
/Users/Standa/Documents/Arduino/libraries/Servo/Servo.cpp:29: error: 'OUTPUT' was not declared in this scope
/Users/Standa/Documents/Arduino/libraries/Servo/Servo.cpp:29: error: 'pinMode' was not declared in this scope
/Users/Standa/Documents/Arduino/libraries/Servo/Servo.cpp: In member function 'void Servo::write(int)':

So I switched to SoftwareServo library, updated this line at the beginning of SoftwareServo.h #include <WProgram.h> to #include "Arduino.h" (it didn't work for me before, I use Arduino v1.0.5) and uploaded this simply code:

#include <SoftwareServo.h>

SoftwareServo myServo;

void setup() 
{
  myServo.attach(9);
}

void loop()
{
  myServo.write(90);
  SoftwareServo::refresh();
}

but NOTHING HAPPENED.
All pins are connected correctly and I tried all my 4 servos, even a different Arduino board and output pins as well as various values of myServo.write().

Do somebody know please what wrong should be it?
I also wonder why Servo library provided by Arduino itself does not work for me and what is an advantage of SoftwareServo library?
Thank you very much.

but when I uploaded this bare program:

a heap of compline errors appeared like this ones:

Where is your #include <Servo.h> ?

Sorry, I forget write it in to my previous post. It's included in the code.

In that case, you've probably got a version mismatch between your library and your IDE, or an incorrectly installed IDE.

On IDE 1.0.5, compiling for a Uno, the code with the #include compiles perfectly.

Please post the actual code and the actual error messages IN FULL - its simply
a waste of everyone's time if you don't.
