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 ...

Full instructions on how to create your very own Arduino music player and alarm clock have been kindly published by Dejan Nedelkovski with all the code you require.

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Instead, Make shows you how to build an internet-connected alarm clock using an Arduino and Google. All you'll need is an Arduino Yúnm a touch screen, a USB speaker, and a few cables.

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.

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 with… ...

The Arduino binary clock shield has been made available via the Crowd Supply website with preorders starting from $33 and worldwide shipping available from $6, and commencing during August 2019.
