Getting your Arduino online - Using the ESP-01 and Blynk

A short tutorial on using the ESP-01 to connect your Arduino projects to the Internet of Things (IoT). The ESP-01 is a WiFi enabled micro controller that may be used standalone or in combination with an Arduino to enable WiFi control and monitoring of any project.

If you have difficulty getting your ESP-01 to work, see my separate video on flashing new firmware:

Hi! It's a super tutorial! I just want to ask you, why you need a 10kOhms resistor for the CHPD pin? Thank you in advance!

[Nicksperiments]

Shouldn’t the ESP 01 have some code flashed to it to communicate to the uno? If I already have code running on the standalone ESP 01 wouldn’t that conflict with communication to the Uno?

i am working with esp8266 nodemcu . can i make the same connections to connect it with arduino uno ??

This is will not work if you're starting with ESP-01. You will run into many issues with ESP-01. You need to check if the firmware from Blynk is installed in ESP-01. Then uploading only will work.

Nice, just need a small help, can i do this woth arduino nano?

[juanjosecamarenacortes]

Excuse me, I get an error in the serial monitor, it says that the ESP-01 is not responding, but I followed all the instructions correctly

Is it OK if I use esp-12e instead of esp - 01 in this project....???

[DigvijayKapdi]

the error " [1609] ESP is not responding " Shows in Serial Monitor, please help me to resolve it.
i use arduino Mega and ESP8266-01 wifi module.

What would I need to change in order to get this working on a Wemos ATMega2560? It has a built-in ESP8266 but it acts as a separate board.

hello. wanna ask, why did you connect the rx and tx to other pins instead of the 0 and 1 pin on the arduino?

[SultanSaeed_]

I connected it like you did put my ESP-01 does not go red, , it just flashes blue when I connect the USB. What could be the problem?

[irfanfakhruddin]

hi, sorry but why my AT says failed to connect to Wifi ?

[j.zweistra]

will this work with sparkfun redboard to ?

[swathisenthilkumar]

Can you please name the components used in this project?

[charuzomag-alasin]

Is there anyway to do this without using resistors???

[Karuniaji]

i tried but it didn't work, esp not responding

[ctbully]

What a Half-Arsed attempt this is ! No Code, No demonstration of the code actually working

[ebaziuk]

So lame, it needs you to make an account with some corporation that then tries to sell you stuff and limits what you can do with your Arduino. This isn't a tutorial it's an ad.
