Working through startingelectronics tutorials (Arduino Analog Value Displayed on Gauge on Web Page) I'm impressed with the available HTML graphic dials & gauges used in the examples & how easy they are to use & customize the scales/ranges BUT only a couple of samples are shown.
Browsing the web I found bindow.net where they have other gauges available including some lower level gauges that you can export as freeware to your own web application BUT it seems the level of HTML supported by Arduino won't allow the use of these in Arduino servers.
QUESTION: Has anyone found any alternative source of gauges / dials for Arduino servers or any details on how to program from scratch.
Regards all.
Like you, I too looked for what gauges were available some years ago.
After a bit of searching I settled on using the steelseries set of gauges for their completeness and customisation. They can be animated with tween with the animation time adjustable.
They are fully coded in javascript and only make use of HTML canvas for drawing, which makes them fast compared to SVG.
The steelseries were initially coded up by Gerrit, and found at his blog http://harmoniccode.blogspot.com
And if you wish to see a demo, head over to this steelseries demo
Do any of these gauges look like they are what you are wanting?
I use them for my own project to display some real time data from my renewable energy system.
You can see that if you head to my signature below and then locate 'HydroSolar'
EDIT: I'm not sure why you say Arduino servers?
If you are setting up a HTTP server on your Arduino, then it still needs to be able to satisfy HTTP requests.
And if part of your project is to serve up HTML and javascript or any other MIME type, then your server needs to be able to do this.
I moved away from using the Arduino as the HTTP server some time ago due to a number of issues that were un-suitable for what I wanted to do.

BUT it seems the level of HTML supported by Arduino won't allow the use of these in Arduino servers.
Just what issues are you having? I think html is pretty much text based and the main limitation on an arduino is memory space. As to text html and other types of files, put them on an SD card and send them to the browser from the SD card.
Thanks RockWallaby for the Gerrit links.
Overall I'm trying to see how far I can go with a Uno / Mega Webserver in providing a very basic Home Monitoring system. I'm suspecting but wanting to avoid as it has been suggested elsewhere that I may need to go for a Raspberry Pi Server for additional features like data logging say using EastIoT and other software.
At this stage I'm just wanting to monitor some gate status possibly with a red/green icon changing colour and other variables like display the number of times a security light may activate by possibly simply counting the number of times a LDR responds. Also want to remotely count my home power consumption detecting the KWHr meter LED pulses. All simple stuff at this stage.
Using a Mega I'll hopefully have sufficient memory for other features like master/slaving some remote I/O points through wireless.
Thanks all
