To design blind walking stick using arduino ultrasonic sensor hc sr04 make the following connections as shown in the connection diagram below.
Smart blind stick using arduino circuit diagram.
The cane can automatically detect an obstacle and give the user a feedback response by vibrating the walking stick and giving a warning sound.
The whole project has been designed on eagle.
One is the main circuit which will be mounted on the blind man s stick.
You can see the wiring diagram from the above image.

Using this arduino smart cane a visually impaired person can walk without anyone s help.
Blind walking stick arduino ultrasonic sensor.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
Using this smart blind stick a visually impaired person can walk without anyone s help.
This arduino smart blind stick project requires two separate circuits.
This arduino smart blind stick project requires two separate circuits.
The main board s circuit diagram is shown below.
The same circuit prototype can be made using a breadboard or zero pcb.
Now it is time for wiring the arduino.
One is the main circuit which will be mounted on the blind man s stick.
A buzzer is connected between d9 pin of arduino and gnd pin.
It cost me just 10 to make one.
Here i will explain by parts.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
That was the simplest way to make a smart stick for blind people using arduino.
Ultrasonic vcc to arduino 5v.
Follow all of the steps mentioned above and after successful testing of the project look for a disable person and offer him this project to make his her life easier.
