Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult with… ...

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.

For example, you could add a real-time clock module to keep accurate time even when the Arduino is powered off, or you could use different colors of LEDs to create a more visually striking display.

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 ...

In this project, PCF85063ATL CMOS Real-time Clock (RTC) is used as the time generator. This provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal. A ...

10 Simple-But-Fun Projects to Make With Arduino John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller.

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.

If you dig DIY clocks or you just think lasers are cool, this is the kind of project that you might want to try, especially if you're getting started with Arduino projects.
