Arduino emotion quantification design, heart rate visualization smart wearable design. The clothing materials are made of PVC pipes and waste newspapers, reflecting the concept of environmental protection and sustainability, while creating a sense of future design. The heart rate sensor and Arduino code are used to design and activate the light strip and air pump. The color of the light strip is changed by the heart rate, and the liquid flows. The PVC tube simulates blood circulation, changes the flow rate of liquid through the heart rate sensor, and visualizes the internal state of the body.
