the former provides better. The aim of this project is to support visually impaired people who travel
indoors.This project mainly deals with the transmission of audio, automatic switching of fan and also
obstacle detection using a setup of PIC microcontrollers, 12 V LED, Ultrasonic sensor and Solar Panel
