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.

Many thanks for this. This has really helped me out. I tip my hat to you, sir.

Great series! I like how these concepts you show are gradually getting more sophisticated! It would be very cool if you could expand on this in a future video, because at the moment only the most recent temperature is stored in the HTML file, whereas saving to a file would also allow for logging previous temperatures. As I'm planning on building an RFID based workplace login/logout tracker, it would be great to just transmit the ID and let the PHP script log it to a HTML with timecode and other info, ideally in a (styled) table of some sort.

Great content! Will an interrupt function break the WiFi connection?

Great tutorial ... Now did you do a followup on GET data from the server - couldn't see it on your site

Thanks man I've really been learning a lot from your videos.

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

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

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

Just starting out with arduino and was wondering: is it able to run a script that makes your computer go to a link
