Could you elaborate a bit on what that might be? A ‘regular’ Arduino doesn’t have internet, so you’d need some kind of shield/breakout to get that in the first place. Then you’d have to struggle with getting the information out.
With the Particle ecosystem, everything works over a REST api. You can use that to send or request data. Retrieving variables can be done using an HTTP GET request, whereas functions may be triggered using an HTML POST request.
For the most real-time option, go with the SSEs, those get pushed from the device, rather than polled. it’s also nicer on the network, since it only transmits data when there’s actually something to transmit, rather than polling repeatedly.
If you browse through the tutorial category on the forum, you should find some nice guides
