I found a template online which I found very useful to use. I am new to using an Arduino overall and I've tried my best to search for the code that can help my project work. My main issue is finding the code that can make a DC motor turn off while a Green LED is on and make the motor turn on while a Red LED is on. All of this is turned on by a button.
The following is the way my circuit is wired and the code
The lines of code that have /* */ were lines of code I found that I tried to make the DC motor work but didn't.

// and the number of study sessions

// period and the number of sessions before
// a longer break. Change these to customize
// your timer!
