Smart Shoe for the Blind || Extremely Useful Arduino Project
HTML-код
- Опубликовано: 16 сен 2023
- Hello Friends,
In today's video, we will learn how to make a smart shoe that can help blind people in detecting obstacle in front of them and thus prevents them from hitting it. This is an extremely useful Arduino project. The obstacle detection is done by using HS RC 04 ultrasonic sensor. When the blind person reaches any obstacle, the ultrasonic sensor detects it and the buzzer goes on. The buzzer sounds the alarm as long as the shoe is near the obstacle.

Informative and practical. Very easy to follow and very neat. Very clear audio. Good job. Expecting more projects and thanks a lot.
Thank you so much dear friiend. Words like these are the motivation for doing more such projects and sharing with everyone. Thanks a lot. 💓
This project is very nice and helpful 😇👌
Thank you dear friend❤️🙂
Super😊👌
Thank you..💓
Those ultrasonic sensors are very cheap, but they get damaged very easily, for instance, wenn you use them to determine the waterlevel in a container, the humidity in the container is enough to damage them
That is true friend. This is only a simple project to demonstrate the idea. Actual version has to be definitely weather proof..🙂
Hello sir male to female jumper wire we need to seperate that 4 nos for sensor and 2 nos for buzzer and 1 for switch right
Yes..that is correct..
Sir the project is good but do we can add a voice assistant to detect the object
Yes..it is possible..I also thought about that. We can add voice alerts using talkie.h library in arduino. But it is a more difficult process. So to make the project simple I used buzzer alarm only..
Hello brother your project is working perfect..but it's buzzering when too close can you tell me how I can add more distance in the coding.. elaborately pls urgent bro!!? :(
Hi friend..In the code there will be following command line at line No. 24
if (distance < 15)
This number 15 is the distance for trigerring the alarm when it detects an obstacle. You can increase this number 15 to increase the distance at which the buzzer sounds alarm..
Thank you so much brother...Even after i succeeded on the functions of these i recommend your channel to my friends for the science exhibition
@@s.vinaysunder8642 okay friend..thank you so much ...I will update channel with more projects...💓🙂
Hey bro can u help me find the codes to put the wires in audino nano?
Hi friend. The same code will work for arduino also. Just make sure you connect to the same pin number...
1. Can you give me the code for the whole function again to add voice instead of buzzer?
2. And if I want to add voice, what separate instruments do I need and what kind of speakers would be good for speakers?
Please reply soon, I have to submit it in my college for project after 2 days🙏😢
Hi friend. I have made a separate video on voice using arduino. You can combine that code and this code which will give voice alerts. You can use any small toy speaker for this.
Sir can we replace piezo in place of buzzer alarm
No friend. We cannot use. The buzzer that I have used just need a DC command voltage to work. So a constant 5V DC signal from arduino is sufficient for it to work.
But in the piezo buzzer, a signal with a frequency (PWM) is required for sounding the alarm. So in the code you have to use the following command
tone(pin No., 1000) where pin no is the pin to which the buzzer is connected and 1000 is the frequency of the signal.
Sir our ultra sonic sensor detecting long objects also and the buzzer is continuously working . What should we do ?
Hello friend..Most probably, it could be a problem with the ultrasonic sensor. If possible please change that and see if the problem is solved.
Before that you can try this. In the code there will be following command line at line No. 24
if (distance < 15)
This number 15 is the distance for trigerring the alarm when it detects an obstacle. You can increase this number 15 to increase the distance at which the buzzer sounds alarm..
hey dude can you tell me what are the types of jumper wires you used(its urgent pls) :(
Hi friend. You need only the following jumper wires
Female to male jumper wires ..4 Nos. For ultrasonic sensor & 2 nos. For buzzer
Hi friend. You need only the following jumper wires..
Female to male jumper wires ..4 Nos. For ultrasonic sensor & 2 nos. For buzzer
With what i can replace the switch? Any ideas where I can find one at my home?
Hi friend, you can get similar switch from old toys. It can be a rocker switch, push button switch, slider switch or anything.
Awsome, any chance that you can help me to transmit the noise in some bluethooth headphones, that would be grate and on another level. But I don t know how to do it@@Science_4U_

Sir where is the link tor speaket? Plz help I have to submit the project next week
Hi friend. In this project, speaker is not given. Only buzzer alarm is there..
I have a question ❓❓ till when will the battery work ?
Hi friend, It will work for many hours. Since there is only a buzzer, ultrasonic sensor and arduino uno, there will not be much power consumption. I think the battery should easily last a full day, working continously. If that is not sufficient, you can use a higher capacity battery.
My buzzer is continuiously working when i attach it with battery
That is most likely because your ultrasonic sensor is faulty. It is always wrongly detecting obstacle in front and the buzzer is continously ON. Replacing with a good ultrasonic sensor should solve the problem.
Will it work with ardeno Nano
Yes..sure friend..👍. Just make sure you give connections to the same pin numbers ..Then only the same code will work.
Hello brother, should the buzzer be passive or active? And can I use a 5v buzzer or it depends on the battery?
Hi friend. It has to be a passive buzzer.You can use 5V buzzer since the arduino output is a regulated 5V, eventhough you may use a higer battery voltage for powering Arduino.
@Science_4U_ so it's fine to use a 5v buzzer on a 9v battery? Thanks for answering me really fast🫶🏼
@mis0o.t522 yes friend. It is perfectly fine..
@Science_4U_ Thank you so much
Only male to female wire right
Yes..all are male to female jumper wires only..
this is great but the "smart shoe" was already done by a kick starter who allegedly took the 250K from backers and dissapeared.
Anyways good luck with these project, just a tip maybe dont use an alarm but a bibration function? so they dont have to make everybody else like panic hehe or maybe do a switch to turn it on and off? Because sadly some people just dont care if a blind person is walking so it may be even better. Who know a zapping device may be great too xD
Yes friend. Your suggestions are great!!!
Dusra switch use kr skte hai?
Yes..bilkul..
Hi sir i am a student of std 6th my school has hold a science exhibition for that reason i have selected your work i have a doubt in it i dont have that machine that you use to connect the wires. Request you will reply. 🙏
I dont have that kind of machines can you help for it?
@@darkslayer009 Hi friend. Are you talking about the soldering iron that I am using to connect wires to the switch?. That is not required friend. You can just insert wire through the hole in the switch terminals and twist it. Soldering is not required.
Ok Thanks sir
heelo dude can you tell me how i can add a voice when the shoe is going to hit somewhere...like a blind person is walking and when there is a obstacle ahead them it shouts "danger ahead"
Hi friend. An audio alert like a speech can be definitely done using a speaker. But there are some commands for converting speech to audio signal and sending to speaker using arduino.. There is a talkie.h library which has to be installed. Then you can use the folowing code for saying some standard words..
#include "Talkie.h" #include "Vocab_US_Large.h" #include "Vocab_Special.h" Talkie voice;
void setup()
{ }
void loop()
{ voice.say(spPAUSE2); voice.say(sp2_THE); voice.say(sp2_TIME); voice.say(sp3_IS); voice.say(sp3_FIVE); voice.say(sp3_OCLOCK); }
Youcan change the words as per your requirement..
Sketch uses 1900 bytes (6%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't set com-state for "\\.\COM7"
Failed uploading: uploading error: exit status 1 what is the meaning of this error and how to fix this error ?
Hi friend. This error says can't set com state for \COM7 means it is not able to communicate to arduino uno through COM 7 port. You can unplug and plug the usb cable connecting arduino. Also after you connect, make sure to goto IDE software..tools..port..select the correct port with a tick mark. Then upload..
Thank you for your reply
The port is automatically selected and I've seen each and every port in the lappi but the same error is generating

Bro can i buy this project
I am sorry friend. I dont sell these projects. You can very easily purchase these components online and make it by yourself..
Can you tell me how to add the code plz😅
Hi friend. First we have to download the code from the link given in the description box below the video. Then, We have to connect the arduino board to PC or laptop using a USB cable. Then we have to open IDE software, which can be downloaded and installed from internet. Open the code from the IDE software and click the upload button. The code will then be uploaded to the arduino uno board..
How many metres jumper wire we need? And hpw much we need
Jumper wires are not sold in metres. It is sold in numbers. Each jumper wire is around 15 centemetres in length and has pins on either end to plug to arduino and other sensors.
For this project you need 4 numbers of jumper wires, male to female ..for ultrasonic sensor ..2 numbers of male to female jumper wires for connecting buzzer..
@@Science_4U_ Near my house it is sold for 30 rs for 1m??
How much wires should I purchase?.
@darkslayer009 okay..but i dont kno2 whether it will have pins at both ends.. what I am talking about can be seen in the following link..

Hii sir I've done this project but only i can see the lights in the arduino uno but buzzer is not working what to do?
Hi friend. Most likely the ultrasonic sensor is faulty and not detecting the obstacle in front. We have to check one by one to find out the exact problem. Have you used this ultrasonic sensor before or is it a new one?
Whether only the power led light in arduino is seen or can you see a flashing led light when the hand is brought closer to the ultrasonic sensor?
I can see the light when hand or any object in the front but buzzer is not working
All the components are new one
The light has to continously blink when you bring your hand near the ultrasonic sensor. The light should go off when you move your hand away from ultrasonic sensor. Is it happening like that?
