This article introduces the **Interactive Emotion Frame** lesson plan, where students use 3 LED lights to create effects like breathing light and heartbeat. They learn basic Arduino programming and electronics, while visually expressing emotions. The modular design is suitable for all ages, offering hands-on experience with technology and creativity

In the winter camp, the kids used **design thinking** to observe life and solve real-world problems with technology. They designed creative projects like a hamster playground and slow-eating reminder device, showcasing the perfect blend of technology and daily life. Over the four-day course, they not only learned technical skills but also developed the ability to observe the world and solve problems.

The children used sound psychology and interactive design to create a "Sound Habit Coach" device that influences habits. They designed the device using the DFmini MP3 module and sensors, observing which sounds trigger responses and using this information to foster habits related to health, learning, and more.
