Hi everyone! Can you help me?

The screenshot tells us very little.

Copying and pasting the error message, along with the code (don’t forget to use triple backticks at the beginning and end) will tell us much more.

Please stop posting screenshots. Copy and paste the code and the compiler messages as described above.

Pete.

I can’t post the code

7

post it as text

8

I did, but then this error has appeared (above)

I guess that’s because you’re not using triple backticks when you post it, and it’s treating some if the text as URLs.
Triple backticks look like this:
```
Put them on a line of their own at the start and end of the code or compiler messages that you are trying to post.
If that still doesn’t work then send them to me by private message, but you MUST include the triple backticks otherwise the code will be corrupted…

Pete.

The syntax for Blynk.vitrualWrite is Blynk.vitrualWrite(VPin,value) so you’re missing a parameter.

Secondly, you shouldn’t be doing virtual writes in your void loop, you’ll flood the server. Read this:
