Create a nice Pomodoro Timer with this fun hands-on project and improve your productivity!

This project is also available at Max Imagination’s Workshop.

Welcome, fellow makers! Today, we're diving into the world of productivity and time management with a hands-on project – the Arduino Pomodoro Timer. This nifty gadget combines the power of Arduino programming with the popular Pomodoro Technique to help you supercharge your work sessions and maintain peak productivity. 

What is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It's a simple yet effective approach that involves breaking your work into focused intervals, traditionally 25 minutes in length, separated by short breaks. These intervals are known as "Pomodoros," named after the Italian word for tomato, inspired by the tomato-shaped kitchen timer that Cirillo initially used.

Before we dive into the intricacies of how our Arduino Pomodoro Timer functions, let's take a quick look at the components you'll need:

How It Works

  1. Set Your Work Time: Make changes in the code where labeled to set the desired work and rest time for each Pomodoro session.
  2. Start: Activate the timer by powering it on, and the LED display will begin counting down the minutes until your break.
  3. Stay Focused: Work diligently until the timer completes a Pomodoro cycle, signaling a break.
  4. Enjoy Breaks: Once the timer reaches zero, the buzzer sounds, and the display resets for your break time.
