"""
Example for trying things out: send one measurement value per minute.

Same as ../deepsleep/main.py, but it waits in machine.lightsleep() instead of
going into deep sleep. Light sleep returns, so the program keeps running in the
loop below and the Thonny shell stays connected - you can watch every uplink. It
draws about a milliamp, against microamps for deep sleep, but far less than an
idle time.sleep(), which would hold the chip at tens of milliamps.

Use ../deepsleep/main.py once the node is meant to run on its own.
