Task Management Box

The following code is for programming the Task Management Box for a College Project during my Freshman Year.
The box allows the user to set a timer for a specific duration using the Keypad and place a phone in a phone cage to avoid distractions.
This enables the user to focus and complete a greater amount of tasks in a short duration of time.
The box included different aspects of electronics including:
Arduino
A servo motor
An LCD Screen
A keypad with numbers from 0-9, A-D, #,$\
