Thinking about various inputs/outputs for the Arduino-based meditation shawl. Was going to go with click button x times = x(10) minutes until lights start up, but now thinking about input from pulse sensor (pulse reduces x amount = lights start up) or temperature. Also could add sound to the shawl. Sound could be an input or an output. Nerds and/or meditators, your thoughts?
Also, the pulse sensor that I found is wired, not e-textile, but I think I could make it work. How often does one through a meditation shawl in the wash, anyway?
