Breathe Project. Scarf that reacts to your breath. As you exhale, LEDs integrated into the scarf begin to glow in sequence. Lilypad Arduino, temperature sensor, conductive thread, bright white LEDs, purple wool yarn. “The Breathe Project is focused on creating awareness of our own breath and the breath of others as a way of reminding and being reminded of the delicacy and life force of each other and of ourselves.” By Hilary Hayes, Ontario College of Art and Design.
