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

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 ...

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 ...

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 ...

Every microcontroller project needs a display. An LCD display with one or two rows for characters is a good choice but it needs several wire connections to make it work. There are seven segment LEDs ...
