A special wearable device based on the Arduino board. Which can be worn on a cloth by using a strip for blinds. The device is equipped with an ultrasonic sensor, motor, and buzzer.

Basic working: When the ultrasonic sensor detects obstacle the device will notify the user through vibrations and sound beeps. The intensity of vibration and rate of beeping increases with decrease in distance and this is a fully automated device.

Powering the modules - Connect the 4 Arduino pro mini to a USB male pin and connect to a power bank. For the module in the hand use a small lithium battery.

Multiple devices can be placed on person's body as follow: two for both shoulder, another two for both knees and one for the hand. Using the five ultrasonic sensors, blind people can detect the objects in a five dimensional view around them and can easily travel anywhere.
