1. Introduction

Wooden digital clocks are gaining popularity as interior decorations these days. I also personally considered purchasing a wooden digital clock for my own home.

When you go downtown, you’ll often see Digital Clocks installed on the outer walls of buildings.
They help to attract people’s attention for advertisement purposes and are also used for decoration purposes.

In this article, I will introduce posts that you can refer to when creating a digital clock.
The title refers to Arduino, however, it can be fully implemented through other boards as well.


2. Time display

First and foremost, you need a sensor that displays the time, the most basic role of a clock.
If you search for ‘7segment’, you will find various options.
In addition to 7segment, you can select dotmatrix or LCD.
It is important to find a product that you like.
In the link below, 7segment is implemented with Arduino.

3. Extra Function

If you use a board that contains the Ethernet chip, it can show the weather with additional functions like the temperature or the date.
For dates, you can retrieve the data just as you use the RTC function to represent the time.
Weather and temperature data can be retrieved via web from sites like openweathermap.
Be sure to check the code that repeatedly reports the weather and temperature to the Serial Monitor through the homepage below.

Let’s take a look at how to get the data, and modify it to output to the desired sensor. (Register to be a member of openweathermap and bring over your own APIkey.)
RGB LED can be used to change colors according to the weather, or they can be shown in characters in OLED modules.

It’s also a good idea to print the weather pattern via dotmatrix. The Dotmatrix example can be found at the link below:

4.Conclusion

These days, you can get a world of information just from searching a little bit.
I hope you’ll try making devices that are suitable for your taste!
