The mood scarf is inspired by the chameleon. Chameleons change color based on their mood, their body temperature, and the light surrounding them. Because mood is directly correlated with temperature, we decided to incorporate a temperature sensor into our project. The temperature sensor takes a person's body temperature, and the code we have created translates the temperature into a color for a mood. For example, the angrier one is, the hotter her body temperature. If someone wearing the scarf is particularly angry, or hot, the LED lights throughout the scarf will appear red. 

Originally, we planned on making a headband rather than a scarf. We ended up choosing a scarf because it can easily conceal the 3D-printed necklace that holds the electronics necessary for our project. The temperature sensor is also able to easily touch the neck of the wearer, which generally gives an accurate measure of body temperature.

Throughout the course of this project, we have used an Arduino Micro to hold and process our programming code. This code is what enables the temperature to be translated into a color, which is then displayed by the LED lights.
