A highly accurate clock made using Arduino, which displays even Temperatures. The clock blinks the colon as well while displaying the time. Even after a power cut the clock displays the current time ...

There’s an Arduino coupled with an RTC module to keep the time, which is connected to the two standard hobby servos mounted in the front panel. A UV LED and simple push button round out the rest ...

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… ...

In this project, PCF85063ATL CMOS Real-time Clock (RTC) is used as the time generator. This provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal. A ...

– Compatible with Arduino UNO – Three Buttons – RTC – Real Time Clock Extremely accurate RTC on board Temperature sensor inside Easy to use with the Arduino “DS3232RTC.h” library ...

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...
