Adjustable Pomodoro Study Timer

Ever since I was in high school, I've been using the Pomodoro method to study, and I really think it's been helping me a lot. It's always better to study knowing you will soon be "rewarded" with a short break.

Therefore, I decided to build a physical, adjustable Pomodoro timer that plays cool songs when a cycle is finished. Hopefully, that'll make my (and any future builders') study sessions more productive and fun.
