Arduino uno usb control 2 servos

Need Help With My Project
1

Hello,
I connect Arduino one your server to serial connection.
When two full servo control can not establish the connection.
what is the problem?
I attach the code to put Arduino:

include SoftwareSerial.h
SoftwareSerial SwSerial(2, 3); // RX, TX
define BLYNK_PRINT SwSerial
include BlynkSimpleSerial.h>
include <Servo.h>
char auth[] = “”; //“YourAuthToken”
Servo servo9; //Variable que utilitzo pel servo connectat al pin 9
Servo servo10; //Variable que utilitzo pel servo connectat al pin 10
//************************************************************************
void setup()
{
SwSerial.begin(9600); //See the connection status in Serial Monitor
Blynk.begin(auth);
servo9.attach(9);//Dic on tinc connectat el servo (pin 9)
servo10.attach(10);
}
//************************************************************************
BLYNK_WRITE(3)
{
servo9.write(param.asInt());
}
BLYNK_WRITE(0)
{
servo10.write(180);
servo9.write(90);
}
BLYNK_WRITE(1)
{
servo10.write(0);
servo9.write(0);
}
void loop()
{
Blynk.run();

}

@Josep, please use code formatting for your posts (edit it and correct your code). Otherwise, it may be deleted.

Does the default example sketch work for you (without servos)?

Here is the troubleshooting guide:
https://github.com/blynkkk/blynk-library/blob/master/docs/Troubleshooting.md

Connect additional USB-serial adapter to see the prints which go to SwSerial.

Thanks, I checked the format code.

I reviewed the code, and it works fine. Attached below the new code.

I do not understand why it says to connect USB-serial adapter to see additional prints will SwSerial, I can explain more?, thank you.

In new code:

@Akash_Raj that’s how it was done in July 2015, now it’s done differently.

Could u plz help me out

@Akash_Raj try to walk first.

You have lots of live examples in your phone that are linked to the live GitHub and IDE examples.
Work through these basic examples to get connected to Blynk and then add the interesting parts like servos etc.

Ensure you always have the latest library version as old versions don’t work with the current server setup.
