please help me out with this

@muthu1995 don’t post anymore screenshots of code. Read the site guidelines and post your actual formatted code.

Did you look at https://github.com/blynkkk/blynk-library/wiki/USB-Serial ?
It’s referenced in the sketch.

See note 1 regarding debug notes.

If you don’t have a USB 2 TTL adaptor then you can’t include the debug parts of the sketch with an Uno that only has one Serial port.
