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
Shoe (A cheap shoe from Walmart is perfect for this project)
Wires (You will need a lot for this project)
Ultrasonic sensor- (Arduino hr-s04)
Push Button switch
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)
