Previously I had alot of troubles connecting arduino to esp8266 to get my sensor values displayed in blynk after watching so many videos regarding it. Then I came across this website:

and now I have a doubt.
Can we connect arduino directly to blynk without any type of connection? Logically I feel we can’t. But in this link they have not mention anything about a WiFi connection or other types of connection so it creates that doubt in me. Can someone give an explanation?

This cloud represents sending data via the internet…

You can communicate directly to a device via Bluetooth, but your phone still needs an Internet connection, and some functionality is missing when using Bluetooth.

You can also do a connection via USB, but that’s not really a long term solution.

The best option is to scrap the Arduino and choose a board that has built-in Wi-Fi…
