The DS3231 RTC module operates at 3.3V. It's essential to use a level shifter or voltage divider if you're using a 5V Arduino to interface with the 3.3V DS3231 module. This is a basic example of ...

This library makes using modules based on the DS1307 and DS3231 RTC really simple. It is compatible with and is meant to leverage the standard C time library <time.h> API (datatypes and functions) as ...

Arduino boards have digital and analog pins that can be used as inputs or outputs. You can also use serial, SPI, I2C, or other communication protocols to interface with more complex devices.

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

Arduino now has an officially supported command-line interface. The project, called arduino-cli, is the first time that the official toolchain has departed from the Java-based editor known as the A… ...
