This site used the Pomodoro Timer as a starting point, but has more features and choices. Specifically this page lets you determine the duration of meditation, how often to hear reminder bells, and even lets you pause and resume your meditation.
Building this was enjoyable because instead of starting from scratch, I saved time by reusing my previous code. It was also rewarding because I was able to apply what I have learned since building the original timer project, which let me know that I am increasing my knowledge and skills.
Best of all, if I am feeling stressed from my code not doing what I mean, I can use this site and try to find peace and tranquility for a few minutes 🙂
