Arduino-based projects are generally powered by AC mains adapters or USB power sources without much thought about power consumption. For portable projects, however, it’s important to reduce energy consumption to increase the battery life for a longer runtime. This includes projects such as portable games or sensor and data-logging projects that don’t have access to external power.
This chapter covers various methods of improving your Arduino project’s power efficiency. You’ll learn to:
Measure the power consumption of your Arduino projects
Estimate project battery life
Reduce Arduino power consumption ...
