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 ...

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 ...

If you live in a place where sunrise and sunset varies a lot throughout the year you know that setting up an automatic ... system to an Arduino that taps into an astronomical clock.

So when we saw this delightfully complex clock designed by [Tucker Shannon ... inside the 3D printed case. There’s an Arduino coupled with an RTC module to keep the time, which is connected ...

The Arduino gets the time from a real-time clock (RTC) module and then displays it using an array of blue and green LED’s. The whole thing is powered using a spare 9V wall wort power supply.
