In this video I’ll show you (without libraries) how to place the Arduino into a deep sleep state – we’ll get this bad boy down to ~0.287uA running the bone stock ATMEGA328P-PU with the Arduino boot loader running at 16MHz with a 5V power supply. I’ll show you how to wake up with a digital input (push button) and from an internal watch-dog timer.
