This is the code for my wordsearch clock!
The main part is "wordsearchClock.ino", used for programming the Arduino.
It relies on the Time library, DS3232RTC Library and FastLED.
The file "gridGenerator.pde" generates a PDF of the letter grid, given an array of letters. The file "Letter_Grid.pdf" is the front face of the clock that I used.
