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!

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.
Make certain that your wifi network ssid info is the same as seen if you were to be logged into you 192.168.0.1 adress, i used the info underneath the router but that was not correct, it works now !!!
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 ?
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.
@@LearningWayz Since the ESP8266 needs access to the internet to send data, it needs to connect to a Wifi. You can start a hotspot from phone and enter the Wifi name and password in the code.
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
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.
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
to do so you might think of some other platform as by default in Think speak the it takes atleast 15seconds to upload new reading/value . in short you cannot change that ,thats drawback of thinkspeak website

Thankyou! I have successfully completed this project.
Hey can you provide abstract for this
Mam plz send me the code once
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
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 ??
I will implement it for a data center controller. I will share my experiences later
How did it go?
Thanks a lot...I have done it successfully

In your video i can see you connected resistors but those are not in CKT diagram?????
No word about resistors. Could you please explain it? Thank you very much.
Resistors on breadboard not connected. Not required
Hi. It's displaying on the serial monitor but there's no change of data on the thingspeak website. Pls what do I do

there is difference between node mcu and wifi module

Is it going to work without the resistors?
thank you very much ,
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

Very useful tutorial ✨
Please what 5 means in the following command : sendcommand("AT+CWMODE=1", 5, "OK");
