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 ...

An Arduino sketch to implement a RealTime clock, which senses your presence using an ultrasonic transducer, and emits the time at minute intervals in morse code. - GitHub - ...

“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 Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...
