The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

About This project uses the NUCLEO-F401RE and Arduino Multifunction Shield to implement a real-time clock and analog voltage display. It shows elapsed time on a 7-segment display and reads ...

README ⏰ Arduino Smart Alarm Clock A customizable smart alarm clock built using Arduino. This project features a real-time clock (RTC) module, an LCD display, and buttons to set and manage alarms.

The Arduino binary clock shield has been made available via the Crowd Supply website with preorders starting from $33 and worldwide shipping available from $6, and commencing during August 2019.

Arduino’s introduction of real-time alerts for IoT projects is a significant step forward in the IoT landscape. It not only enhances the functionality of IoT devices but also makes them more ...
