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 ... We like the super-cap circuit he added to keep the RTC running if the power is cut. Is an Arduino overkill here?

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 ...

Inside is a RTC (real time clock) with battery backup for timekeeping along with an Omron 5V relay to drive the garden lamps themselves. This particular relay comes with a switch that can force ...

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 ...

Dejan Nedelkovski has built a stylish DIY touchscreen Arduino music player and alarm clock which has been created ... that has been compounded with a RTC module and 3.2 inch touchscreen, which ...

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 ...
