Is it necessary to sleep in a loop?

[leecallen35]

Sorry I realize this is a noob question. On any other platform I would put a sleep in a loop so the program does not monopolize the CPU. Is that necessary & appropriate in micropython on the Pico?

Thanks.

That is generally useful if you application can accepts a delay up to 1 ms. Best call machine.idle().
