Make Your Own Binary Clock
From Kalle Wallin on Hackster.io:
A couple of years ago I wanted to try out some iot-related stuff. I bought a couple of Arduino-boards and some random components and started fiddling around. At first I started out by trying some experiments such as temperature controlled LED lights and blinking stuff that reacted to sound. After this I wanted to get my feet wet and actually build something, preferably geeky, not necessarily very useful. Binary clocks have been an interest of mine for years. They kind of force you to take a step back and reflect on time, what time is, what is time and so on, and maybe slow down the frantic pace of modern life for a few seconds. Or not, but I like them anyway!
