Step 13Extensions: Range Finding
One of the attachments for the Arduino Watch is an ultrasonic range finder. This one is a Maxbotix LV-EZ2 (from SparkFun) and the watch is reading the pulse width modulated signal from the sensor.
In future versions I may route the output to a vibrating motor or speaker to allow for someone with visual impairment to use the range finder as a cane.
