send commands to esp8266 via Arduino

Hello I use a esp8266. I can communicate with the esp without any problems over the serial monitor.

If i use the code from page Arduino:Getting started with ESP8266 WiFi Module – Techwithabhi

 #include <SoftwareSerial.h>  
 SoftwareSerial esp8266(2,3); // make RX Arduino line is pin 2, make TX Arduino line is pin 3.  
                // This means that you need to connect the TX line from the esp to the Arduino's pin 2  
                // and the RX line from the esp to the Arduino's pin 3  
 void setup()  
 {  
  Serial.begin(9600);  
  esp8266.begin(9600); // your esp's baud rate might be different  
 }  
 void loop()  
 {  
  if(esp8266.available()) // check if the esp is sending a message   
  {  
   while(esp8266.available())  
   {  
    // The esp has data so display its output to the serial window   
    char c = esp8266.read(); // read the next character.  
    Serial.write(c);  
   }   
  }  
  if(Serial.available())  
  {  
   // the following delay is required because otherwise the arduino will read the first letter of the command but not the rest  
   // In other words without the delay if you use AT+RST, for example, the Arduino will read the letter A send it, then read the rest and send it  
   // but we want to send everything at the same time.  
   delay(1000);   
   String command="";  
   while(Serial.available()) // read the command character by character  
   {  
     // read one character  
    command+=(char)Serial.read();  
   }  
   esp8266.println(command); // send the read character to the esp8266  
  }  
 }

I will receive a lot of crap signs, see the attached picture :confused:
