Smart Piggy Bank
Interactive Saving System
An interactive system designed to encourage saving in children. Integrates smart technology with a friendly design, using renewable energy and sensory feedback.
Interactive Feedback
Reminders via vibration and LED lights.
Sustainable
Powered by integrated solar panels.
Smart Control
Regulated by a controller for saving goals.

Project Concept
My final project is an interactive Smart Piggy Bank. More than just a simple money container, it is an educational tool that uses sensory feedback (vibration and lights) to remind and encourage the habit of saving in children.
The added value of this prototype lies in its sustainability, integrating a solar panel for battery power, and its tactile design, covered with a silicone-like material to make it pleasant to touch.


Design and Fabrication
The design process involved multiple digital tools such as Inkscape, Tinkercad, and CorelDraw. The main structure was fabricated using 3D printing, optimizing internal spaces for electronics and storage.
- 2D design for cuts and templates.
- Parametric 3D modeling for the casing.
- Surface finish with soft materials (silicone/leather).

Electronics and Programming
I based my electronics on an alarm clock design to understand the logic of timing and alarms. The system was programmed in the Arduino IDE environment.
I fabricated two board versions; although the process was challenging due to my limited previous experience in electronics, I successfully integrated vibration control, lights, and solar energy management.
Conclusions
There is much room for improvement, such as the location of the power supply and the optimization of internal spaces to reduce costs in future versions.
