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 ...

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 ...

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.

Here arduino is used for reading time from ds1307 and display it on 16x2 LCD. DS1307 sends time/date using 2 lines to arduino. A buzzer is also used for alarm indication, which beeps when alarm is ...

Discover a 3D-printed DIY 7 Segment Clock powered by Arduino Uno, stepper motors and a DS3231 RTC module. Designed for tabletop use, it features precise mechanical movement and digital control, making ...

RTC with LCD Display Project (real time clock) This project demonstrates how to use a DS1307 RTC (Real-Time Clock) module with an LCD to display the current date and time. The program reads the RTC ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

Libraries used: OneButton (improving button functionality) HT1632-for-arduino (interfacing arduino with Sure Electronics led dot matrix) EEvar (storing variables in EEPROM memory) In order to install ...

Hardware -------- Because this is an extension of the original generator the basis will be the same Arduino Uno I was allready using. A prototype shield carries the real-time clock based on a DS3231 ...
