    Arduino-powered Hexadecimal Color Code Clock

    element14 presents  |  Matt Eargle's VCP Profile |  Project Videos



    In the socially-distanced, work-from-home apocalypse of Southern California, clocks have become obsolete as time has become essentially meaningless. After months of no longer using an alarm clock, Matt has missed the simple act of checking the time--even for curiosity's sake--and decides to build a clock that measures the passage of time in a completely novel way: by converting hours, minutes, and seconds into hexadecimal values and displaying the relative color value associated with that time. It's certainly not the most practical chronometer in the world, but this hexadecimal color code clock proves that form doesn't always have to follow function!
