i got it is video pe jo circuit or code hai ok tested hai tnx bro apne itna detail me guide kiya

Good video. I did it. It works. Thank you! Beware! 2 problems: 1. SoftwareSerial does not work correctly at baudrates>9600. As I couldn't change the ESP8266 to anything other than 115200, I used the hardware serial pins. But, when you upload the code, you have to disconnect the ESP8266 Tx and Rx pins. Also, you can't use the serial monitor for debugging. 2. I used the Arduino Nano which only furnishes 50 mA on the 3.3V pin but the UNO doesn't do much better and the ESP8266 can consume 150mA or more in certain cases. I used an AMS1117 3.3V regulator connected to an external 5V power supply to make everything work. Once I did those 2 things, it worked like a charm!

Thanks man, the best explanation of how to transmit data on on IoT device.

I get only fail msg on the serial monitor.... How to solve this condition?... Plz explain about the progrm

Thankyou! I have successfully completed this project.

Can anyone explain what im doing wrong, I connected the arduino like in the video, i uploaded library and code but ESP wont connect to wifi ??

Great work, I have a Q plz, if I want to send max30100 data how could I send the heart beat for Field1 and oxygen to Field2, plus i have LM35 sending the data to Field3

Thanks a lot...I have done it successfully

For this project, the arduino board is not required. A RS232 FTI interface may be used only to program the ESP8266-01 then the server is operating with the ESP8266-01 board alone.

is there any configuration for esp8266 module ?? how about the setup for beginners?

The temp thingspeak did not get displaying the data. also, I did not get any error message. should esp lighting when its working or not?

big fan sir, mur project tu hol sir apunar video sai apuni assam r neki baru? joi aai axom

thankyou bro very helpful

Thank you!

I will implement it for a data center controller. I will share my experiences later

Will it work if i use dht22?

Is it going to work without the resistors?

Instead of ThingSpeak is there a way for the value to be sent to google sheets?

my AT command is fail why is this happen in the serial monitor? help me

May I know, you have uploaded the program in the Arduino and not in the ESP8266-01 chip ? Did you make any changes in the ESP8266-01 firmware or did you upload any program in the ESP8266-01 chip also before making this video ?

Nice one thank you

Thankx man

Hi. It's displaying on the serial monitor but there's no change of data on the thingspeak website. Pls what do I do

thank you very much ,

Tnx for the video But...... the esp-01 is an 10 times more powerfull processor as an Uno You can put everything in the ESP and it will work and 10 times faster.

Can anyone help to get code......from video 3.40 i am not getting

hai sir i am using this code with uno it works properly when i connect it to mega at fail command appears on serial monitor. how can i solve it plz help me

Hi, I would love to know why you have added those resistors in the circuit but I can't see them in the circuit diagram you shown earlier in the video. Can you please explain how to know where to add resistors and why? Thanks for the tutorial though.

No word about resistors. Could you please explain it? Thank you very much.

Thanks man! Works like a charm for me :)

Thank You

thankyou

thanks a lot

Doesnt work, softwareserial esp8266(rx tx) redeclared as different symbol

Data is not uploading in thingspeak. When i saw in the serial monitor it was showing API fail. Can anyone give me solution? It's urgent

How can I set the sendig time? Becuse it send the datad (temperature and humiditi) about every 10 sec. I can save energy. Thanks a lot.

I am getting error at esp8266

would i be able to use a arduino nano with this code

I would like to thank you for that video. I had a project where I had to do exactly that and I spent hours upon hours trying until I fond your tutorial. Thank you!

no resistors on circuit diagram come on!

nice

I tried everything but it always "fail"

If anyone have full correct code plz send

Please send code for this.

I am getting errors while compiling the code

Thanks for all of this :) Now im trying to see if i can set this to send info every 10 minutes :)

Why he put a lot of resistors?

Bro code is expired

Work, but i don't have all datas on ThingSpeak... Thank you !

Send me the code bro to try

can someone help me? it fails to send data to thingspeak 0. at command => AT Fail 0. at command => AT+CWMODE=1 Fail error! warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] sendCommand("AT+CIPCLOSE=0",5,"OK");

Can anyone help to get code......from video 3.40 i am not getting
