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 ...

The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...

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 pets need to be fed timely so that they could maintain good health. The pet owners aren’t available at the home 24/7, sometimes they go for business meetings to another city or someone else’s ...

A cloud service was utilized to process, store, and provide users with remote access to the collected data. Google’s App Script was chosen because it is free and can be easily modified in a language ...

This is a mini-NTP based on a ESP32. Time will be provided from the GPS receiver and a DS3231 if no GPS-signal is avaliable, to server time to your networkcleints. With the feedback and help from our ...
