Circuit diagram of the Arduino real-time clock with temperature display is shown in Fig. 3. It is built around Arduino Uno (Board1), 5V regulator 7805 (IC1), 2.4cm SSD1306 OLED display (DIS1), DS3231 ...

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 data and displays the date and time on an LCD ...

This project demonstrates how to create a digital clock using an Arduino Uno, a DS1307 real-time clock (RTC) module, and a 16x2 LCD display. The clock displays the current time (hours, minutes, and ...

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, ...

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 ...

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 ...

“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 ...

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 ...

Project Hardware Software Selection. The Arduino Uno is a microcontroller board based on the ATmega328. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as ...

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 ...
