It takes a handful of LED arrays with an integrated driver, an Arduino Nano, a real-time clock module, and a voltage regulator. The software uses a custom 6×9 font and handles addressing the LEDs ...

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.

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 ...

This project aims to build a digital clock using a real-time clock chip (DS3231) with battery backup, a liquid crystal display (JHD 204A), and an Arduino Uno board. Let us try to design our own ...

With help of Real Time Clock Module, the device can know what time it is. Disadvantage of this model that I used is that it’s not accurate and it misses around 5 minutes every 24h, so it’s not ...

“Here is the Kraztech Real Time Clock (RTC) Module that uses the Microchip MCP7940. The Kraztech RTC Module is intended for the opensource Arduino platform but can easily be used with any ...

This 3D-printed mechanical clock uses three stepper motors controlled by an Arduino Uno and a real-time clock module. Each digit is powered by cam-driven segments with rubber bands helping reset the ...

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual intervention. It is built around an Arduino Uno, which is programmed to ...
