Anxiety Necklace
Arduino wearable tech project by Laura Ospina is a necklace that changes colour based on mood using a temperature sensor at the back of the neck:
This necklace displays a person’s anxiety level according to body temperature. There is a temperature sensor placed on the back of the neck to get accurate readings. According to these readings, the RGB LED placed within the necklace locket will light up in different colours.
For this project, the lilypad Arduino was used. It is also placed at the back of the necklace. This is a piece that accentuates your feelings as an extension of yourself through the light in the necklace.
