Very Low Power Arduino / Battery Power - even Micro-amps!

We're going to learn how to make an Arduino consume as little power as possible whilst still being fully functional! We'll look at the basic Arduino devices (with the ATMega328 processor) and learn how we can use it in a low power environment such as data logging where we may be running totally off battery. I show that it's possible to use the Arduino down to microamps!

thank you about arduino sleep mode It seems like the easiest thing to organize. It was very helpful in completing the project using the watch dog timer.

nice work

Your video is very useful for beginners.
At time stamp 3:35 you make a comment about the current not being like an "Original Arduino". This is dis-ingenious as the schematics are different between the clone Nano and an original Nano. If you look at the two schematics you will see that the onboard regulator of the original is connected on both cases, the USB and external 5V. On the clone nano the on board voltage regulator in NOT connected in both cases. This is why the current is lower on normal operation on USB power. When on battery power the on board regulator is always being used and the USB chip is always being powered.

One thing I found interesting after I’d made the video is the chips on the nanos weren’t the same either. One had the ATMega328p the other the ATMega328PB which I believe aside from offering lots of extra features does also consume a different amount of power. Crazy eb
