IoT Remote power switch

Using a Ethernet seeeduino and a wired network, it will get an ip address and display it on a OLED display. Using this address in a internet web browser it will display a red or green socket and enables you to change the relays state via a output pin 6. The graphics are done with html 5 SVG so the browser does all the work.

i have attached a new sketch with fixes for chrome, and a tweaked library to fix some errors when using version 1.6.3 sketch.

Folks!

Monitoring several news feeds about browser developments gives some signs that SVG supportr in popular browsers will end soon. A possible alternative would be to load a graphic from an web page. This requires minimal data in the sketch.

Ok, I found the link to say SVG is dead and it was dated 2010. SVG wasn’t widely used, but since ie9 and Firefox having native support it has been gaining some ground.

To my knowledge SVG is not part of HTML5. There are some other mechanism in HTML5 which might replace the Need for SVG. -AH-

For the past 4 years browsers have been supporting SVG natively, it look like the need for plug-ins are losing support. SVG support is part of html5. could you provide a link's to the news feeds you have found? Thanks, Malcolm.

Do you know what are they planning to use instead of SVG? Regards, Clemens

Hi malcolm,

SVG is definitely giving web-based displays a new impulse, but the implementation is still buggy. On my PC running Windows 7, in Chrome (40.0.2214.115 m) the images are cut, in IE 11.0.9600.17633 everything looks fine. See attachements below.

Regards,
Clemens

Hi Clemens, I did see that in Chrome, and thought it might have been a bug in the version that I tried, with it working fine in IE. I did use a Arduino Uno and Ethernet shield with a relay module to do the testing before boxing it up in a smaller footprint. Thanks for you comments, Malcolm.
