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 ...

Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and GND to the ground rail. For the data connections, wire SDA to Pin 10, SCK ...

With the assumption that you’re just as enamored with these oddball chronometers as we are, we present to you this fantastic digital tachometer clock ... an Arduino Nano, a DS1307 RTC ...

The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module. The RTC module is crucial for keeping accurate time, even when the Arduino is powered off. It maintains the time using a ...

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 ...

Now picture that same issue over dozens of clocks in a train station, or hundreds in a school or factory. It’s no wonder that slave clocks, which advance on signals from a master clock ...

DIYer Paulo Renato's solution was to hook up his lighting system to an Arduino that taps into an astronomical clock. The Arduino ... an on/off switch, a Tiny RTC, a time adjustment button, and ...
