Zuhaib Ghauri, a fifth-grade studnet from Karachi, has developed a navigational hat for blind people which helps them walk without bumping into hurdles. The child prodigy came up with this innovative idea after completing his Arduino courses. Powered by batteries, the hat uses sensors and an Arduino board to identify the hindrances in the way.
The sensors, working as eyes for the blind, can detect the obstacle in three dimensions: left, right and front and calculate the distance of the barrier and sends a signal to the board, which converts them into specific sounds. Arduino is an open-source platform where programmers design and share single-board microcontroller kits for building digital devices.
