Hello. I am trying to make a simple device that will randomly play up to 5 short mp3 files at random times during weekdays between 7am-4pm with a random delay of one hour up to 4 hours. It is for a harmless workplace prank. Using DS3132 RTC module and dfplayer mini mp3 player Here is my code so fa…
