LED NeoPixel Digital Clock

thingiverse

For some time now, I've been eager to bring a large-scale LED-based clock into reality. Behold, the result. Using these files, each digit is approximately 11 inches in height. A strip of 30 LEDs per meter has been employed, with three LEDs per segment, and a single LED in the colon segments. An Arduino Nano serves as the brain, running the entire operation alongside a DS1307 chip to maintain accurate time - even when turned off. Three buttons are integrated into the design. When the clock is operational, the hour and minute buttons adjust their color. Briefly pressing the setting button changes the colon color. The clock boasts customizable colors for hours, minutes, and colon segments, allowing users to choose from red, orange, yellow, green, cyan, blue, purple, magenta, "harlequin", colour fade, and white. The harlequin option displays each segment in a different color that fades across the rainbow spectrum. Colour fade, on the other hand, gradually transitions the entire digit through the colors of the rainbow. Pressing the setting button down for two seconds puts the clock into setting mode, enabling users to modify the time (simply press and hold the hour/minute buttons to adjust). Briefly pressing the setting button toggles Daylight Saving Time on and off, while holding it for two seconds sets the time and returns the clock to its normal display. This project is still in development, and my programming skills are self-taught. As such, they may not be the most efficient methods. Furthermore, this design relies on several support libraries; please consult the #include lines to determine which ones are necessary.
