Arduino Low Power - Creating a LoRa IoT Node That Runs off Batteries

By ShawnHymel

We build on our previous LoRa IoT weather sensor to run for a year on 2x AAA batteries. We'll look at the AVR ATmega328p datasheet to determine which registers we need to use to put the microcontroller to sleep, and we'll calculate how long we need to sleep before sampling the sensor again.
