In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock ...

The best of the suggestions in the Twitter thread brings us to the Arduino Entropy Library, which uses jitter in the microcontroller clock to generate truly random numbers that can be used as seeds.

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 ...

Project Overview The voice-controlled Arduino-powered clock uses a real-time shield and a MOVI Speech Dialog Shield connected to an Arduino.

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… ...

Arduino’s real-time alerts for IoT projects offer a powerful tool for enhancing the efficiency and effectiveness of IoT devices.

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.

Some of the first steps toward working with Arduino is understanding how to write code for it. The good news is that it's made with beginners in mind.

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino.

Instead, Make shows you how to build an internet-connected alarm clock using an Arduino and Google. All you'll need is an Arduino Yúnm a touch screen, a USB speaker, and a few cables.
