 String value;
 int TxD = 11;
 int RxD = 10;
 int pos = 90;
 SoftwareSerial bluetooth(TxD, RxD);
 void setup() {
  Serial.begin(9600); 
  bluetooth.begin(9600);
  myservo.attach(9);
 }
 void loop() {
  Serial.println(value);
  if (bluetooth.available()>0)
  { 
  value = bluetooth.readString();
  if (value == "aabra ka daabra")
  {
