It all started when my father wanted to build a Wordclock as a Christmas present. He asked me if I could help him with programming the clock. I had never programmed Arduinos before and had to read up on peculiarities such as pointers and libraries.
We faced various challenges: daylight saving time, flickering, NTP. Next, I want to install a brightness sensor so that the letters are easily readable at midday in the sun, but also at night.
