The heart of the clock is the Arduino Uno, a versatile microcontroller known for its ease of use and flexibility. The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module.

I like this. Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a ...

In this project, PCF85063ATL CMOS Real-time Clock (RTC) is used as the time generator. This provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal. A ...

Meanwhile perhaps it is time for the Arduino folks to re-appraise their documentation. The subject of entropy and generating random numbers is one that has appeared on these pages many times.

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino.

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 ...

Below the 3D print of the moon the clock shows more traditional data thanks to a 0,96” OLED screen. It not only displays date and time, but also air moisture if you need to know of such things.

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino… ...

Sean took an antique clock an removed the mechanisim, and then replaced it with an Arduino, that is programmed to check the weather on the Environment Canada website every fifteen minutes.

Sick of telling time the old way? Spice up your time-telling time with the open-source, hackable and Arduino -based DOTKLOK. Basically, you can get a bunch of different ways to tell time.
