Best Way to Optimize Power Consumption in an Arduino-Based IoT Project

Hi everyone,


I’m a student working on an IoT project using Arduino, and I need to optimize power consumption since the device will run on a battery. I’m considering using sleep modes, reducing clock speed, and optimizing code execution, but I’m unsure which approach will have the most impact.


Would a low-power microcontroller like ATmega328P (Arduino Pro Mini 3.3V) be a better choice than a standard Arduino Uno? Also, what are the best libraries or techniques to efficiently manage power in an IoT system?

Any advice would be greatly appreciated!

Thanks!
