Introduction: Smart Cap

Good vision is a precious gift but unfortunately loss of vision is becoming common now a days. Blindness may result from a disease, injury or other conditions that limit vision and because of which Blind people confront a number of challenges everyday. and navigation is one of them and solution is smart cap it helps in navigation

Step 1: List of Materials

ARDUINO - 1 I had used uno pro mini is recomended

ULTRA SONIC SENSOR -3

MOBILE PHONE VIBRATOR -2

SMALL BUZZER -1

POWER SOURCE FOR ARDUINO

Step 2: Schematic's

the ultrasonic sensors has 4 pins

1) vcc

2)gnd

3)trig

4)echo

connect all the vcc and gnd pins of all the sensors to the pins of arduino vcc and gnd

sensor1

trigPin1 arduinoA0
echoPin1 arduino A1

sensor2

trigPin2 A2

echoPin2 A3

sensor 3

trigPin3 A4

echoPin3 A5

left vibrator vcc to arduino pin 5 (left sensor is 2) gnd to gnd

right vibrator vcc to arduino pin6(right sensor is 3) gnd to gnd

Buzzzer gnd to gnd and vcc to arduino pin 3

i

Step 3: Code

if you want to increase range you can simply change the distance in the code at this part

if (distance < 45)

Step 4: Arrangement of Sensors

place sensor 1 at the front part of the cap

sensor 2 at the left side of the cap

sensor 3 at the right part of the cap

place the vibrators in left and right sides of the cap

Step 5:

Step 6: Conclusion

the only drawback of the cap is it can sense the objects only at the height range of the sensors

if you people want you can make some thing like smart shoe and am currently working on it and want to improve it using open cv and raspberry pi and microsoft hope you guys like this project if you like it dont forget to vote my project thank you :)

if you have any quires feel free to ask in the comment section :)
