What is the reason behind writing `tNow = millis();` twice, i.e., once in `setup()` and once in `void requestData()`?

It should have been `tLast = millis()` to initialize it in `setup()` as your starting time.

Consider and try ` tLast = 5000;` initialized in `setup()` before starting the `thread()` and observe what that will do.

Write some code with `millis()` in `setup()` (more than once and different locations) and` draw()` and use `println()` to examine the values.

I write a lot of simple snippets of code to examine how they work and a better programmer for it.

See the references for `setup()` and `draw()` as well to understand them.
