(MOD) Mobile Obstacle Detector for Blind People

This report describes an embedded system which is purposely developed for helping
blind people and people which have very critical visual impaired. It is called (MOD) mobile
obstacle detector. Theproject is focusing on helping those people in detecting obstacle in front of
them. The project objective is to build one simple device that can easily handle by blind people
and people with visual impaired to detect any obstacles in front of them. The device will be
designed with button as ON/OFF button. Userjust needs push one buttonandthen use it like we
use torchlight. The device has a capability to detect any obstacle and warn user about the
obstacle. Before user hit the obstacle the device will warn and alert the user about the obstacle so
user can more alert and avoid the obstacle. The concept is like using torchlight so it provides
freestyle handling with unlimited pointing. For normal people they use torchlight to see in dark
situation. Same goes to blind people, they can't see, but with this device the obstacle can be
detect and user will be warned. The device will use ultrasonic transducer as a sensor and
PIC16F877A microcontroller will do the computation. Hopefully, this device will help those
people and brings a lot ofbenefits to them.
