In this article, let\u2019s do one more exercise, and the exercise name is Productivity Timer<\/strong><\/span>. I call it a ProTimer<\/strong><\/span>. This application tracks your productive working time.<\/span><\/p>\n

That means the one usecase of this application could be it tracks how many hours you study or work productively in a day. <\/span><\/p>\n

Before you start studying or working, you set the time for how many minutes you want to study. And then, you can start the timer, and you study or work until the timer expires. <\/span><\/p>\n

And the application tracks the productive time, and at the end of the day, you will come to know how many minutes or how many hours you spent productively in a given day. That\u2019s a usecase of this application.<\/span><\/p>\n

We will build this application in this article using the state machine approach. Before that, let\u2019s know the requirements we need to implement in this application.<\/span><\/p>\n

There are a couple of components in this application. All the components are connected to the Arduino Uno board.<\/span><\/p>\n

– 16×2 LCD<\/a><\/span><\/p>\n

-Three user buttons<\/span><\/p>\n

–A couple of resistors to interconnect all the components<\/a><\/span><\/p>\n

–A buzzer: an active buzzer<\/a><\/span><\/p>\n

–A Potentiometer: Its purpose is to set the contrast for the LCD.<\/a><\/span><\/p>\n
