Need Help With My Project
1

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: http://help.blynk.cc/en/articles/512056-how-to-display-any-sensor-data-in-blynk-app

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?

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…
