#Power Management of Atmega-328p (Arduino nano) with RTC used for wake-up (DS3231) This sequence displays the possibility to save power by keeping the processor in sleep mode.

Inside the boxy blue base is an Arduino Nano, a DS3231 real-time clock module, and a perfboard full of transistors for switching the LED strips inside the segments.

The Raspberry Pi Pico is both faster and cheaper than the Arduino Nano, but the nano has better resources and community.

In this article we discussed how RTC Module works and how we can interface it with Arduino to build DIY Arduino digital clock.
