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.

Arduino has recently introduced a new way to create triggers and notifications in its Arduino Cloud. Enabling real-time notifications for ...

This enables the Arduino to report the time to the VIC-20 via its IEC port. The project is a neat way to provide a real-time clock source to programs written in Commodore BASIC.

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 ...

Discover how to build a real-time event notification system by integrating NodeMCU (Arduino) with Google Firebase and Laravel. This tutorial covers the complete setup, from hardware to cloud and ...

Connector to add external battery to real-time clock (RTC) inside Renesas MCU (MCU RTC power pad held to 5V rail on Minima) Secondary (wireless) processor: 240MHz 3.3V dual core 32bit Espressif ...

Arduino enthusiasts, makers and hobbyists looking for inspiration for their next project might be interested in a unique Arduino clock aptly named the Time Slider.

Microcontrollers: real-time collaboration in the Arduino Cloud Arduino's Cloud Editor now allows developers to program together in a project. A paid Arduino Cloud subscription is required.
