You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino.

In this project I wanted to learn about the usage of a Real Time Clock Module (RTC Module) using arduino. For this simple project I followed some guides online in which all the code and schematics are ...

A highly accurate clock made using Arduino, which displays even Temperatures. The clock blinks the colon as well while displaying the time. Even after a power cut the clock displays the current time ...

A small CMOS clock module, such as the one presented here, is not capable of offering as much precision as a clock module built around a microcontroller. However, it can still provide a variable clock ...

Because the real time clock module is so accurate, there’s no provision for setting the time. [Barzok] says that twice a year he just hooks the Arduino up and reflashes the program with a new ...

In the movie 2001: A Space Odyssey, HAL 9000 — the neurotic computer — had a birthday in 1992 (for some reason, in the book it is 1997). In the late 1960s, that date sounded impossibly … ...

Next, you’ll need an Arduino board, which will serve as the brain of your weather clock. You’ll also need a motor shield to control the movement of the clock hands, and a Wi-Fi module to ...
