I like this. Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a ...

In this project, I used a clock that needs a 3AAA battery to run, which is 4.5V in total. I linked it's positive and negative to the 3.5v pin and ground of the Arduino, and it works Lastly, close up ...

Esoteric clocks are something of a staple among hardware hacker projects. If it can be made to tell the time correctly, even if only twice a day, the chances are someone’s made a clock from i… ...

The other is a DS3231 real time clock with built-in crystal. A CR2032 keeps it all running. The main body, the outer ring, the bottom, and the buttons are 3D printed in PLA.

Scrolling Clock - Arduino UNO, RTC, and DHT-11 Hey Science Enthusiasts! Get ready to dive into the world of Arduino with a fantastic project: a 64x8 LED Dot Matrix Clock with temperature and humidity ...

LED colors come in red or green. The only down side is the price (starts at $150). But if you gotta have one, you can buy them here. Hands off videos [vimeo 19947676 w=620 h=400] ...

Nixie tube clock build has been classed as an intermediate project and should take approximately eight hours to complete using an Arduino MKR WiFi 1010 microprocessor together with IN-1 Nixie ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Okay, I knew this would happen - one Arduino clock leads to another. Take a look at a clock that tells the time in terms of the first 192 digits of Pi, via a 32 x 8 LED matrix... Dubbed the Pi Day ...
