I asked how can i connect my ESP8266 module to Arduino and Blynk

I believe this instructable will help.

Sorry, didn’t noticed that. But there are plenty of answers to this question. Just cross the Serial lines, and provide level conversion between. That’s more or less all you need. And of course the firmware to run on both. The AT firmware on ESP and your ‘sketch’ on Arduino.

All are talking just out of topic.

Not really… just debating the issue of why ESP & Arduino. Your question has been answered hundreds of times actually all throughout this very forum.

And I gave you a solid answer… but if you can’t or won’t search… then you will find yourself with lots of problems in life.

We are here to help you learn about Blynk, not take your order and ask if you want fries with that, each and every time asked… when there’s a whole buffet right behind you, ready for the taking

Click on this topic from just a few days ago (about one of the key components of linking the two)… read to the end and click on the next topic link I included at the bottom, and the next, and so on

EspSerial(2, 3); // RX, TX

I want to connect an ESP-01 to an Arduino Uno board, and I want to use software serial. I am confused by this line in the example code provided by Blynk: EspSerial(2, 3); // RX, TX Does that mean I should connect: ESP RX to Arduino pin 2 ESP TX to Arduino pin 3 or is it vise versa?
