144 7-segment displays make up this delightful digital clock
January 29th, 2020—
Using 7-segment displays to make a clock is nothing new, but what if you combined 144 of them together to create an epic LED timepiece? That’s exactly how this project was made, allowing it to show surprisingly smooth mega-numbers and a colon set at an angle.
The build itself is controlled by an Arduino Nano, along with an RTC module for timekeeping and 18 MAX7219 drivers to activate over a thousand (1,008) individual segments.
One could see this used for a variety of purposes, perhaps as a scoreboard for sporting events, a scrolling display, or even as 36 little clocks, which can actually be seen below.
