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 ...

[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232… ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano.

The clock relies on an Arduino Mega to run the show, with an RTC for timekeeping and a temperature sensor to boot.

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 ...

Time Slider clock “A digital clock using sliding grids to show or hide the segments of the digits. Each minute the sliders move in a synchronized manner to show the current time.

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...

The DS1341RTC real-time clock (RTC) integrates an AGC circuit for dynamic drive-current adjustment to ensure that the device consumes the least amount of current required for operation.
