Arduino Continuous Rotation Servo

hello everyone,

i working on bot project , have taken portions of robot , spread them out. im working on wheels far. have 2 continuous rotational 'servos' powering wheels. having trouble code it. on basic stamp used pulsout() unreliable , sketchy, on arduino uno rev3 using, trying best rotating set amount of time. know not possible code in degrees want turn, using servo.microseconds(x) able delegate direction , how fast turns. x being 90, stays still, above 90 , turns clockwise, below goes counterclockwise.

my issue timing. want servo turn set amount of time. have tried loops, loops, while loops, , such. reason servo keeps spinning.

any suggestions helpful? run issue before?

just quick example of 1 of quick tests tried,

code: [select]

#include <servo.h>

int time=0;
int degree;
servo myservo;


void setup()
{
  myservo.attach(9);    //sets pin 9 servo
myservo.writemicroseconds(90);   // sets servo not spin
}

void loop()
{
  do
  {
    degree = 180;
    myservo.writemicroseconds(degree);
    delay(500);
    time = time + 1;
  } while (time < 20);
 
  myservo.writemicroseconds(90);
}


in example, servo continuously rotates, never stops , wont delay have set. seems gets stuck on myservo.writemicroseconds()

i think have 2 or 3 errors.

when use writemicroseconds() parameter must number between 1000 , 2000. still using degree values. 90 deg corresponds 1500 microsecs.

you have no delay() after writemicroseconds() after while loop there no time servo react.

you don't reset time 0 before while loop loop work once because after time have higher value test.

while not cause of problem have no serial.println() calls in code assist see going wrong.
