Serial Communication - Arduino UNO and ESP8266 (ESP-01)

Nice explanation thanx

I found this tutorial after 3 hours of trying to figure out why mine wasn’t working, I just went into run app data and deleted the old eps8266 folder I had and then re downloaded the same version he used and it magically started working!!! Thx so much

Interesting. Thank you.

So i need to upload code to esp01?

thank you very much, this is the most complete tutorial

how did you have the virtual serial com port? I can't do it cause I have only one com port

Realy a working tutorial

Why i cant reset the esp-01 after doing this ?

Thank you very much.
I have been searching for a couple of weeks, and your video is the ONLY one that gave a complete solution; meaning covering the programming stages (code + connections) on BOTH ESP2866 and Arduino!
Best regards.

Fantastic tutorial!

do i need to connect both arduino and esp usb to computer?

Sir esp-01 gets disconnected from wifi after few seconds. Can you please help me.

can i use the RX and TX pins for communication as well?

wow, the video has some audio problems, but the content and code it's great, thanks for sharing

Thank you my friend👌

This was the straight forward tutorial I was looking for! Once the 3.3v regulated is powering the esp8266, its digital output are still recognized by the 5v arduino inputs. However, in a perfect world I would use a voltage divider to lower the digital output from the arduino to esp @ 3.3v. OK, Im going to try. Thanks you :)

Dude, that's a great tutorial, tnks for sharing.

Why do you need the Regulator if you can just use the 3.3V from the Arduino

I am getting this error , I am using without regulator and using 3.3 v. raise FatalError('Failed to connect to %s: %s' % (self.CHIP_NAME, last_error))
esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header the selected serial port does not exist or your board is not connected. Can you please help ?

why did you use software serial ? you could have left in on de hardware serial ports .. or is it a must ?

Is possible to send and receive serial data between ESP-01 and Arduino UNO in same time.

thank you! it finally works

You're probably the only one (I watched) so far that explained how to connect ESP-01 and Uno (Nano perhaps), nice and good job friend.

I can't communicate using software serial. Whyy? Help me please

I wasted a lot of time looking through written tutorials and nothing really got to what I was looking for. This was great. I finally have a telnet server that I can use to communicate with an arduino remotely!

Uploading this sketch on ESP, does the firmware erase?

Do you have idea about Esp8266 wifi module? I have a problem. AT Commands doesn't work. It only displays reversed "question marks". Thank you again

Amazing tutorial!! Thank you so much <3

Hello! what if my port is not clickable?

This is best out there. The others are really not for beginners.

You connect ESP uart (3 Volts !) directly to Arduino Uno uart (5 Volts!) ??? Are you OK?
ESP may be damaged!

Why haven't you level shifted tx & rx channel btw 8266 and uno?
As per data sheet 8266 tx and rx are 3.3v reff

please Make a project on "ARDUINO UNO with ESP8266 & 8 CHANNEL RELAYS" and program it..... 🙏🙏🙏🙏🙏

please make a “PROGRAMMING" video on “ARDUINO UNO with ESP8266 $ 8 CHANNEL RELAYS" and control by Android phone....🙏🙏🙏

why are you using 5v from Arduino and then converting it to 3.3 volt with regulator instead of using 3.3 volt form Arduino
and the tx pin of arduino which uses 5v is connected to rx of esp it will kill th esp8266.

Outstanding tutorial! You don't miss a single detail. I followed these steps and everything worked perfectly. Much appreciated.

Also, I did this without the 3.3 Voltage regulator although I haven't done any long term testing.

Can I use esp8266 together with Hc05 bluetooh module using 1 arduino uno board

Sir Thank You

Can i use the 3.3V from arduino directly....without using the voltage regulator?

In My case It is showing an Error: "Failed to connect " Even the connections are same as in the video.. plzz help me to resolve this issue.

What if we connect rx to tx and tx to rx?

Sir i try this on esp o1 and uno it is working perfect but when i trying on Arduino mega 2560 it show nothing on serial monitor with all communication pins what i can do?

Thank you so much!!!!

My adruino is only receiving data if i disconnect the pin 2 for a very short time. Anyone encountered this problem before?

LD1117v33 noting it down for my reference.
1- Arduino ground
2- 3.3v output (+)
3- 5v from arduino

sir, great tutorial.. hats off to you.. sir, i have a question though, id be really grateful if you answer my doubt.. When, we upload the code to esp, does that mean we have- flashed the firmware and uploaded a new firmware (which is our code) , or is the original firware still there along with the program that we have just uploaded (to the esp)..

Great explanation, thank you.

url???

You could directly receive 3.3 volt from arduino board and u did not need to use a voltage regulator
