Introduction: Arduino - Help Blind Person to Walk Safely (Ultrasonic Sensor).

This is a device that is generally mounted on the user’s head. It uses ultrasonic technology to detect obstacles and other objects that are located in front of the user’s path. The sonic mobility device uses the musical scale’s 8 tones to indicate the distance of the object. Each tone signifies a particular distance from the obstruction. The user hears the tones through the device’s earpiece.

The sonic mobility device is suitable for outdoor use. However, it may not be used in places with extremely loud noise. This device should be used with a cane or a guide dog.
