If you're a new convert to practising Yoga for health or meditation reasons, one important factor to take into account is your breathing during various positions. Over time it becomes easier to control your breathing, however if you're just starting out or wish to be more conscious about your breathing style, then the following project by Bonnie Barrilleaux, Sachi Decou, Jamie Piazza, Melanie Goetz and Amanda Galvin.
As part of a women's hackathon they created an Arduino-powered device that uses a wind sensor mounted on a headset to help measure the breathing of the user. This is then converted to data which is displayed using an LED strip wrapped around a cylinder, for example:
After a small amount of calibration and practice, the user can then receive visual feedback about their breathing levels and take better control of the entire process. This is a fascinating and useful example of what can be done with an Arduino, so visit the project page to learn more and recreate your own.
