Interactive Wooden Flower was designed in the framework of the “Mobile and Wearable Computing” course during my Medialogy studies at Aalborg University in Copenhagen. The flower opens and closes due to the movement of a servo motor positioned at its center and connected to an Arduino Nano 33 BLE. Initially, the flower’s movement was controlled by the “LightBlue” mobile application, which was later replaced by an ESP32 M5Stack Atom Matrix serving both as a physical controller and a keyholder, enabling a more tangible and entertaining user interaction. Communication between the flower and both the LightBlue app and the ESP32 M5Stack Atom Matrix is facilitated through Bluetooth Low Energy (BLE).

The ESP32 device features an LED matrix that provides expressive visual feedback: a smiley face appears when the flower opens, and a sad face when it closes. This is triggered by a button press on the controller, making the interaction more playful and intuitive.

The goal was to create a tangible, playful, and interactive object that reacts to user input in real time, bridging the gap between digital and physical interaction.
