Write POST Data to Server with Arduino Uno with WiFi

The information on your website and in the video was instrumental in helping me post data from the Arduino Uno WiFi Rev 2 to a website. One problem I struggled with was an error in the php code line 3 or $tempF = $_POST["temp"];. I was having problems so I started checking the error logs in my FTP application and found the following: Undefined index: temp. I changed line 3 to the following: $tempF = $_POST['temp'];. Maybe this problem is server specific. Just wanted to post this to help anyone encountering the same problem.

That was so helpful...there almost isnt any support for wifi and http protocols... This helped clear a little.

Thanks, got me kick started. Posting data all day long to my server. But, once the data is posted, I'd like to return data to the Arduino, just pass a few variables. 1) Post data to server, 2) Do some calculations with that data 3) Return some data to the Arduino. Could be as simple as 22,54,12

Thanks for making the time to teach me. Great video. Super approachable.

Fantastic video. Exactly what i want to do. Been learning python, html ,css , bootstrap to accomplish that goal.

Excellent. Thanks for your video. That was my missing input.

Thanks man I've been searching this for a long time now really Thanks

Ohh !!!! Let me tell you that you are a saviour. I am a beginner with Arduino and almost spent a week to do this. I was looking for ESP-01 with arduino to achieve this. But here you are !! Thanks a lot. GOD bless :)

This guy is a Legend, when i started learning computer classes back in 2009 i saw some of his videos! A legend indeed!

Very nice, useful, helpful and smart way to view data from Arduino to anywhere in the world. Best
