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
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
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

Code
if you want to increase range you can simply change the distance in the code at this part
if (distance < 45)

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

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 :)
