Arduino Nano 3.0 (ATmega328). Real Time Clock DS3231RTC. 32x8 LED Dot Matrix Display Module (with MAX7219 chip). LDR sensor.

This project came about because of my fascination with watching the LED Cube tutorial from Tapendra Mandal on YouTube. LED cube's primary purpose is to serve as a decoration. It is created in a way in ...

We’re big fans of the impractical around here at Hackaday. Sure there’s a certain appeal to coming up with the most efficient method to accomplish your goal, the method that does exactly what it needs ...

The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...

Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a ...

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 ...

There are LED clocks, and then there are LED clocks that can blind you from 30 paces. [Stiggalicious’s] LED ring clock is of the latter variety. 200 WS2812B/Neopixel RGB LEDs drive the ring clock to ...

Hard drive clocks are a dime a dozen on sites like Etsy, but Hacked Gadgets reader NatureTM went the extra mile and employed an Arduino to control the time and LED light show on the reflective ...
