Grove real time clock: keep track of time!

This small Grove RTC module accurately and regularly measures passing hours, minutes and seconds. It also allows you to count the number of passing days, months and years, adapting automatically to months having less than 31 days and leap years.

This RTC Module is calibrated through to 2100! You can also set it to obtain the time in either 24-hour or 12-hour format (AM/PM).

RTC: a Grove module that makes life simpler

If you’ve not yet discovered the Grove universe, this real time clock will provide you with a now-or-never opportunity to give it a go! The Grove system is designed for electronics beginners and for all those wanting to develop projects more quickly and easily.

It revolves around a central base shield, to which you can then connect a multitude of Grove modules. Everything can be programmed with the Arduino IDE. No welding, no complicated connections… welcome to Grove!
