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 ...

In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

Arduino enthusiasts or those looking to build a binary clock may be interested in a new shield created by developer Marcin Saj. The binary clock shield ...

The Arduino code merely needs to request the time from the RTC whenever it is required, rather than deal with the decoding itself. Is it overkill?

There’s an Arduino coupled with an RTC module to keep the time, which is connected to the two standard hobby servos mounted in the front panel.

Arduino enthusiasts, makers and hobbyists looking for inspiration for their next project might be interested in a unique Arduino clock aptly named the Time Slider. It might not be the quietest ...
