transmitter will be held by the blind person, once they press a button on the transmitter, the

walking stick will start emitting a beeping sound.

Any normal stick could be used for this project. We will be interfacing a Raspberry Pi to the

walking stick. At the end of the stick, we will attach an Ultrasonic sensor with GPIO pins of Pi.

At the same place, we will be connecting our camera module. Both the sensors must be facing

the same direction for an accurate reading. The components must be connected with a network

to process the images in order to identify the obstacles.

Hardware Required for the Project

• Raspberry Pi for the image processing ...
