I am having trouble integrating the RTC into the code along with the buttons. Like stated in the post I am wanting my motor to turn on at a programmable time which can be set via buttons.

There are many examples of the RTC with the Arduino, consider looking at an alarm clock.

Oh my dear,

there is more missing ... If I am not wrong you have only a number of messages that are scrolled left/right and back with quite a hugh number of delays.

See here on Wokwi:

There is a long way to go ...

Hi @gilshultz: It's 23:25 o'clock at home .. I quit for today ... :wink:
