My CR servo won't stop rotating.

i have continuous rotating servo. press spin counter-clockwise , c clockwise. , b stopping it. i'm not pressing buttons , servo still pins. slowly. because of voltage? or servo broken? servo needs 6.6v , arduino can supply 5v servo still turns.
here code btw:



#include <servo.h>
 
servo myservo;

int pos = 0;

void setup() {
  // initialize serial communication:
  serial.begin(9600);
  // initialize led pins:
 myservo.attach(9);
}

void loop() {
  // read sensor:
  if (serial.available() > 0) {
    int inbyte = serial.read();
    // different depending on character received.
    // switch statement expects single number values each case;
    // in exmaple, though, you're using single quotes tell
    // controller ascii value character.  for
    // example 'a' = 97, 'b' = 98, , forth:

    switch (inbyte) {
      case 'a':
        for(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' asdddddddd
    delay(5);                       // waits 15ms servo reach position
    }
        break;
      case 'b':
       myservo.write(80);
       delay(10000);
        break;
      case 'c':
          for(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
           }
        break;

  }
}
}

is 80 write cr servo stop it?  seems odd.
