How to use Esp8266 with Arduino Uno

[VG-vnkk]

Thank you so much! Simple, clear and just works! Tested my Esp8266

No mention that you're putting 5V on the ESP-01's RX pin coming from the Arduino. This is not guaranteed to not fry your 8266 chip because its inputs are supposed to be limited to 3.3V. This is generally a very bad solution, but sometimes you can get away with it. Sometimes not, and you get yourself another ESP-01.

please I’m getting this error : Invalid head of packet (0x00).

Please what do I do ?

[jananathbandara]

looked mulltiple videos to get code. only code that worked without issue.

[rajkecy]

why didn't you use a voltage divider circuit to connect esp8266's RX to arduino's TX?

Thank you for the video. My sketch is working fine now. Actually we need to download the ESP9200 library in Board Manager first, which you didn't mention.

Hi,

I hope this message finds you well.

First of all, I want to thank you for your incredibly helpful videos. I watched your tutorial on using the ESP8266-01 module that you uploaded a year ago, and I successfully connected my ESP01 to my WiFi following your instructions.

However, I am now facing some issues with connecting my ESP01 to Blynk using an Arduino. Despite watching numerous videos and reading several guides, I haven't been able to get it to work.

Here is what I've done so far:
1. Connected my ESP01 to my WiFi successfully.
2. Followed your tutorial on how to use the ESP01 module.
3. Tried various wiring configurations and different pieces of code to connect to Blynk, but without success.

Could you please guide me on how to properly connect the ESP01 to Blynk using an Arduino? I would also appreciate any advice on the correct wiring setup.

Thank you so much for your time and assistance. Your videos have been incredibly helpful, and I'm hopeful you can help me resolve this issue.

its not getting connected, its showing connecting to wifi only, what should i do?

[JasonOpong]

Are you using the esp8266 esp-01? I see from the white markings that your module is different.

Could you please leave a link for the source of the module ?

Is there no use of resister to protect esp8266

[ghostwar]

do you have a video where you to telegram bot using arduino uno and esp8266 like in the video?

[vinicioeufrazio]

for some reason my wifi doesn't connect, it just keeps "trying to reconnect", even with the correct credentials

[supersongs]

Bro one problem. The serial monitor is come trying to reconnecting pls help

[rifkenji]

i have done a connection like you do and unfortunately the esp doesn't working and when it connected to power it blinking blue light and then disappear. You also don't show part of the esp8266 is working properly like showing the light. please make a useful video instead of just playing around
