My fascination with butterflies started 2017 summer in Arnhem. I was visiting the Netherlands for the first time to see my friend, while thinking of studying there. During this trip, as my friend loves animals, we went to the Burger Zoo together. And thatโ€™s how I entered the butterfly garden for the first time.

The moment I stepped in, I was in full shock. I just stood there, mesmerized by the dozens of butterflies fluttering around me. As big as fists. As light as disposable tissues. Like the ones you blow your nose at. Moving as if they are not bound to the concept of time. Moving around so easily, pushing the air so effortlessly with elegance.

While preparing for the graduation show, this memory sprung up again. Yes! Perfect excuse to dive into this fascination. With a slight twist! Like...๐Ÿค” butterflies with QR codes!!

I mean, imagine people chasing QR code butterflies with their smartphones. Just picturing them awkwardly chasing and trying to scan the fleeting butterflies tickled my brain and made me laugh.

Starting with the butterfly toy brought from Korea as a reference, I decided to reverse engineer this toy. I mean... how hard could it be?

Well, as a person who knows very little about programming languages and has almost zero background in electronics,
the making process of this QR code butterfly was continuous Above all, it was such a slow process.
But the day had come. It took A WHILE, but I finally checked all the .







...!


As all the components were ready, I pressed to run the code in Arduino.
