Reducing Arduino Power Consumption

When it comes to portable electronics, one of the most important features is how to maximize the battery life. The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but as you’ll see in this guide, we can drastically bring that down with just a few tricks. In this guide we’ll see if we can reduce the supply current to less than 10uA with a couple hardware and software tricks.”
