Can somebody help me in my project ?
Please edit your post and replace the screenshot with the text copied and pasted from your compiler error message.
Put triple backticks at the beginning and end of the the error message test so that it displays correctly. Triple backticks look like this:
```
Copy and paste these if you can’t find the correct symbol on your keyboard.
Also, add your sketch, also with triple backticks at the beginning and end, along with details of the hardware you are using and the version of the Blynk library you have installed.

You appear to have created a second username on the forum, and re-posted the same screenshot under that username as well.
Your second user account has been deleted along with the posts made under that account.
Please do not do this again.
Also, when you create a “need help…” topic you are prompted to supply a fa be of information.myou haven’t done this in this topic, or the topic you created with your other username.
If you had done that, you may already have your solution by now.
Pete.
