Title
“The Story of a Butterfly”
CONCEPTION AND DESIGN
The concept of this project is the life story of a butterfly. While seeking inspiration, I noticed many interactive Arduino bionic projects focused on the fluttering of butterfly wings. These projects are fascinating and beautiful. However, few pay attention to the butterfly’s early life stages. Initially, they are not the beautiful creatures we imagine, but green, unattractive caterpillars on branches, vulnerable to becoming bird prey. Only after hard work and a long wait do they emerge as stunning butterflies. My project aims to showcase this transformation, incorporating interactive elements during the caterpillar and cocoon stages, using a butterfly model with Arduino motors and Strips to emphasize the beauty and create a visual impact, prompting viewers to reflect and appreciate.
FABRICATION AND PRODUCTION
1. Scheduling:
First, we assessed the main tasks and established a schedule. Our steps mainly involve creating the computer screen background, decorating the backdrop, and crafting the mesmerizing butterfly. Next, we concealed a servo motor and white thread based on the butterfly’s size to ensure it initially remains hidden at the top of the device, then can fully emerge. Finally, we installed a pressure sensor at the bottom to achieve interactive effects.

2.Production Process:
The focal element in our project’s construction was the butterfly, crafted using 3D pencils to enhance the depth and beauty of the 3D experience. We integrated a motor sensor, selected for its ability to demonstrate controlled rotational movement, which activates when users press a button. Initially, a larger motor was considered, but its size and weight were impractical. Alongside this, a pressure sensor narrates the butterfly’s story. The coding process involved transferring data from Arduino to the processing unit, vital for both the butterfly’s story and its 3D representation.

CONCLUSIONS:
To summarize the project’s conclusion from a different perspective: Our primary aim was to highlight the often-overlooked butterfly story. Reflecting on the project, I see room for improvement, especially in increasing interactive elements, as suggested by our audience. My understanding of interaction aligns well with the project’s design. Given more time, I’d enhance interactivity with additional sensors. This project taught us valuable lessons in time management, prioritizing, and the efficiency of collaborative work. Our teamwork was exemplary, and our combined ideas and learnings from the semester have the potential to make a significant impact.
