Helps blind walk without stick. Very cheap and effective :-) :-).

Installed in cap to keep your hand free!!!

Step 1: Things Required

1. Arduino UNO
2. Ultrasonic Module HC-SR-04
3. Jump Wires (F to M)
4. Jump Wires (M to M)
5. Connecting Wire ( to connect Arduino to Computer to Program it)
6. Buzzer
7. A Cap

8. Breadboard ( Not much needed)

Step 2: Connections

• Connect the "Trig" pin of sensor to pin 9 of Arduino
• Connect the "Echo" pin of sensor to pin 8 of Arduino
• Power the sensor
• Connect the "-ive" of buzzer to "Gnd" of Arduino
• Connect the "+ive" of the buzzer to pin 10 of Arduino

Step 3: Programming Code

Write a code by yourself if you wish so or i have the code.It is below:-

Step 4: Finishing Touch

Now attach this to cap such that the sensor is in the front side of the cap.

Interesting idea. Have you by any chance had a blind person try it out? I'd be curious about their feedback.

Thanks for sharing this!

Thanks for your reply. I have made a blind try this and it worked out inside house nut outside it is not possible with small rage distance sensor. instead of the sensor that i use can be replaced by some long range sensor then it can be a perfect solution for visually impaired persons
