The yoga breathalyzer is a breath visualization tool to help you understand and get in touch with your breathing. Breath is the basis of yoga and meditation, and this biofeedback tool is one way to develop a deeper understanding of your own breath. Using Arduino, a headset-mounted wind sensor, and an LED strip, it's simple to translate your breathing into visual output.

Step 1: Collect supplies

For this project, you will need:

Arduino Uno
Soldering equipment, break-away header pins, and wire (rainbow cable works great)
Anemometer (wind sensor) such as this one: http://moderndevice.com/product/wind-sensor/
Wireless headset
2 meters WS2812 LED strip, such as this one: http://www.adafruit.com/products/1138
Plastic cup and a single white sock (great use for that lonely sock that lost its partner)
9V DC barrel jack power source
A cup or bowl to cover the sensor so there's no wind during calibration
Brilliant! Love it.
I like this idea very much.When I have time,I will DIY.It is so wonderful
So Cool! If you add some video - I would love to feature this project :D
I added a video of the yoga breathalyzer in action!
