Servo control: extremely confused noob

hello everyone,
i absolute newbie, please forgive me if
a. has been asked before (see below)
b. it's in wrong sub-forum

i have been trying mini servo working time. want rotate 60 degrees on button push , stay there. when button pushed again, want come zero.

i have tried searching , found similar (though not identical) problems. have tried using suggestions, keep getting stuck @ same point.

what happens when run sketch , press button, servo rotates few degrees (about 5, guess) , comes zero. if long press push button, servo rotates in 5 degree steps , after 4 or 5 presses swings zero. tested servo using sweep sketch in examples , servo rotates without problem.

since mini servo, powering off arduino board. once basic structure right , use multiple servos using separate power supply. have put in 10k resistor in circuit. rest pushbutton , servo.

please take @ code , tell me doing wrong. regular toggle switch work better want do?

thank guidance , pointers.

code: [select]


#include <servo.h>

int servopin = 9; //servo on pin  9
int buttpin = 3; //push button on pin 3

servo servo01; //plan have many servos

int pos = 0; //servo position
int buttonstate = 1; //reading button state

void setup()
{
  servo01.attach(9); //servo atached
  pinmode(buttpin, input); //button initialised
  pinmode(servopin, output);
}

void loop()
{
  buttonstate = digitalread(buttpin);
  if (buttonstate == high)
  {
    for(pos = 0; pos < 60; pos = pos+1)
    {
    servo01.write(pos);
    delay(10);
    }
  }
  else if (buttonstate == low)
  {
    for(pos < 60; pos = 0; pos = pos-1)
    servo01.write(pos);
    delay(10);
  }
}


please show how button wired.
