Hello, today we will be creating a shoe for the visually impaired. Such a device can make blind people blend in along with normal people and not make them stand out as when using a white cane. This can bring about significant improvement in confidence and quality of life of the visually impaired.

Step 1: Materials

Arduino UNO

Bread Board

Shoe (A cheap shoe from Walmart is perfect for this project)

Buzzer

Wires (You will need a lot for this project)

9V battery

Ultrasonic sensor- (Arduino hr-s04)

Push Button switch

220ohm resistor

Foam Board

Total cost= < $65

Step 2: Putting Together the Project

Two long wires are required for the buzzer because the buzzer will be going to the user's ear.

Step 3: Code

The code is attached- I based my code of Mert Arduino and Tech's code. ()

Step 4: Building a Casing for the Hardware

Cut 2 rectangular 6-inch by 3-inch pieces from the foam board

Then cut 2 rectangular 3-inch by 1.5-inch pieces

Finally cut out a rectangular 6-inch by 1.5-inch piece ]

Before gluing, take the 6-inch by 3-inch side and score the box about 1.5- inches from the end of the 6-inch side make sure you go across the full 3 inches. Also, be careful that you don't cut the piece into 2

Glue the pieces together to create a rectangular box, Make sure the side that was cut on the 6-inch by 3-inch is placed on facing the inside of the box. (Look at example photos for reference)

After the box has been created cut a small square near the top of the box on the 3 inch by 1.5 inch for the wires to exit.

Step 5: Attaching the Box to the Shoe

To attach the box to the shoe I used glue, electric tape, and nails

First glue the box to the sole of the shoe

Then press half-inch nails from the inside of the box into the sole of the shoe (I used 6, but I think 2 should hold)

Finally, tape the box to the shoe

Step 6: Installing the Hardware

First tape the wires for the ultrasonic sensor to the tip of the shoe

Then depending on the type of wires you used either solder or place the ultrasonic sensor into the wires.

Then attach the push button switch to the bottom of the shoe

Finally, solder the buzzer to the two long wires.

(I added a plastic piece to hold the buzzer on the user's ear)
