POMODÍN - Active Pause Robot With OLED and Potentiometer

Greetings. We are students of the Unidad Educativa General Julio Andrade, located in an agricultural province in the north of Ecuador. We are currently in high school and motivated to improve the way we learn and organize ourselves, we have developed this technological and educational project.

We present “Pomodin”, a robot based on the Pomodoro technique, designed to encourage study with active breaks in a fun and efficient way.

Operation :

Every 45 minutes the buzzer sounds to announce a break time of 5 minutes and the game (optional play) is put on the screen for 5 min, then it goes back to work. During work time, Pomodin is reading with his little eyes.

Components to use:

1. I2c OLED screen
2. 1 Potentiometer
3. Arduino Nano
4. Piezoelectric chip
5. Power regulator
6. Protoboard
7. Wires
8. Robot chassis (Box or any decorative container)

1. We used a recycled box as the base to create the shape of a robot. With extra cardboard, we added arms, legs, and a head.
2. We cut openings in the box to place visible components: eyes (LEDs), mouth (buzzer), and belly (button).
3. The robot was decorated with paint and recycled materials to give it a fun and eye-catching appearance.

1. The Arduino was placed inside the robot’s body, with space organized to fit the buzzer, LEDs, and button.
2. Components were secured using double-sided tape or recycled supports, leaving only the necessary parts visible on the outside.

1. Before assembling, we created the circuit design digitally using [Tinkercad/Fritzing or your tool].
2. The design included an OLED screen to display the countdown, a potentiometer to adjust the time, and a buzzer to signal the end of each cycle.
3. This step helped us visualize all the connections and ensure the layout was functional and organized.

1. We uploaded the Pomodoro timer code to the Arduino, setting up work and break intervals, the OLED screen, and the buzzer.
2. We tested each component, made final adjustments, and closed the robot for presentation.

As students from Ecuador and from a productive area we are pleased to assure that “Pomodin” is a study assistant with an educational and playful purpose. It helps to maintain concentration, reminding us that it is also important to take active breaks, it is an ideal tool for students and school environments.
