Blink works fine in standalone but code I wrote only works when rest pressed

hello everyone,

i looked on , cant find specific issue.  i load code using arduino platform , place atmega328 in breadboard, blink works fine (without having press reset button).  however, code below works if press reset button.  after pressing reset button works fine.. i'm baffled i've seen surrounding breadboard atmega328 issues don't seem address unless i'm not connecting dots.  i keep thinking i'm missing in loop setup i'm having problem finding it.

any appreciated.  this first time i've created code adding someones existing code...

code: [select]

//bluetooth portion of code created by: angelo casimiro (4/27/14)
//voice activated arduino (bluetooth + android)
//feel free modify remember give credit
#include <servo.h>
string voice;
int light = 2; //connect led 1 pin #2
servo servo1;

void setup() {
 serial.begin(9600);
 serial.read();
 pinmode(light, output);
 int servopin=9;
 servo1.attach(servopin);
 servo1.write(0);


}
//-----------------------------------------------------------------------//  
void loop() {
 while (serial.available()){  //check if there available byte read
   delay(10); //delay added make thing stable
   char c = serial.read(); //conduct serial read
   if (c == '#') {
     break;
   } //exit loop when # detected after word
   if (c == '*') {
     voice ="";
     continue;
   }
   voice += c; //shorthand voice = voice + c

 }  
 if (voice.length() > 0)
 {
   serial.println(voice);

   if(voice == "servo on")
   {
     digitalwrite(light, high); //turn on led
     servo1.write(90);   //move servo 90 degrees
     delay(100);
   }
   else if(voice == "servo off")
   {
     digitalwrite(light, low); //turn off light
     servo1.write(178);   //move servo 0 degrees
     delay(100);
   }

   //-----------------------------------------------------------------------//  
   voice="";
 }
} //reset variable after initiating

assuming have pull-up resistor on reset pin, might try add diode reset pin +5vdc, cathode wired +5vdc , anode reset pin.

current design used in uno , solve intermittent problem such seeing 1 had hit reset have sketch start after upload. small signal diode work.
