Read the time and play games on this Arduino-based word clock
If you’ve been interested in creating a word clock for your home, then perhaps this neat build by “oliverb” will be the perfect place to start.
The clock, powered by an Arduino Nano along with a RTC module, is capable of displaying the time by spelling it out as you expect, or can use the letters as a matrix in order to show the time in digital format. These letter-dots can even be configured to form an “analog” clock if you prefer.
But that’s not all. The device can reveal the temperature and humidity, as well as play games like Tetris. Be sure to see it in action below!
