My clock was inspired by the “Cookie JAR clock of passion” (https://hackaday.io/project/175830-cookie-jar-clock-of-passion) by Marius Taciuc.
I used an Arduino Uno with a DS3231 clock module and 4 alphanumeric displays. This clock gives also messages, phrases of some Beatles songs. It was built as a birthday present for my Gerda.
It gives the phrases almost every hour, between 9 AM and 11 PM.
