Publish/Read a Variable to/from the Cloud - Particle.variable() [Video Tutorial]

Feedback is appreciated!

Question with regards to data usage. When it’s looping is it constantly writing that value to the cloud or is it only sending/receiving data when the rest request is received?

You ask the cloud, the cloud asks your device, and the values comes back in reverse order. It should thus only use data (for variables) when asking for them. There’s still the cloud connection in the back that’ll have to be kept alive, which uses some data.
Any particular reason why you’re asking?

I hear that AT&T Uverse has data caps (though they don’t often enforce them) and if it was firehose that data out to every time loop fires it could have me hit the limit. Glad to know it’s not doing that.
