“When I saw these 7 segment displays with FeatherWing backpacks on Ask an Engineer, I got really excited. I love clocks! I have the original Ice Tube clock from Adafruit, plus the PiGlow daughter card binary clock, plus my collection of watches (including a programmable TI digital watch that I’ve re-programmed to display Martian Standard Time and the current Sol). So the thought of having a mobile clock with a colored display made me immediately run to the shop and buy three colors (and a Circuit Playground, but that’s for another tutorial). This clock design uses NTP (Network Time Protocol) to always display the accurate time, synchronized to the same clocks that run the Internet!”
