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 (RTC) IC that is simple to use, low cost and ...

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 ...

[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232 ...

We’re big fans of the impractical around here at Hackaday. Sure there’s a certain appeal to coming up with the most efficient method to accomplish your goal, the method that does exactly what it needs ...

Real-time environmental monitoring is increasingly important in agriculture, industrial automation, smart homes, and healthcare. The real-time data monitoring ...

Dejan Nedelkovski has built a stylish DIY touchscreen Arduino music player and alarm clock which has been created using a folded piece of sheet metal to provide a minimalist yet clean enclosure to ...

Arduino enthusiasts or those looking to build a DIY binary clock may be interested in a new shield created by developer Marcin Saj. The Arduino binary clock shield has been made available via the ...

I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

Arduino uses a 32bit counter to provide a millisecond by millisecond timing reference. It is called ‘millis()’, and being 32bit, it overflows at about 4billion in ...
