Build a clock with Arduino that tells time via colors

This Arduino-powered clock tells time in colors

from arduino.cc

As humans, we’ve divided time up into 24 hours per day, 60 minutes per hour, and 60 seconds per minute. With many of us now working from home on differing schedules, time may seem a bit less concrete than before, like something that fades from one part of the day to another.

To express this new reality, e14 Presents’ Matt Eargle has constructed a clock that cycles through “every” color in the rainbow, subbing in a scaled version of the HH:MM:SS time value for RGB values on a 5” LCD TFT display.

The build is powered by an Arduino Uno with an RTC module for accurate timekeeping. The resulting color panel is quite interesting, if not so useful for, say, catching a train. If you do need to be punctual for something, the actual digits are shown along the side, so it should still be usable when things are (hopefully) a bit more normal.

If you're interested in making your own version, PMD Way has you covered with a huge range of parts including Arduino-compatible boardsLED displaysjumper wires and more.
