Running on batteries does not carry your Arduino project very far? Well, when you want to run an Arduino project on batteries, you have to spend some thoughts on minimizing power consumption. Here we will look at what you can do when you use an AVR MCU. Often you will be able to reduce the average current consumption to a few microamps!
