Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult without some ...

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 ...

Just when we thought we’d seen all the ways there are to tell time, along comes [mr_fid]’s Berlin clock build. It’s based on an actual clock commissioned by the Senate of Berlin in the mid-1970s and ...

Building your very own Nixie tube clock is becoming easier and easier thanks to sites such as Nixie Tester and custom-made new boards. Such as the Arduino Nixie tube clock shield that is compatible ...

A new Arduino binary clock has been created by the La Fabrique DIY team, which has been inspired by the architecture within Paris and is powered by an Arduino Uno development board together with 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 ...

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. The alarm clock is made ...
