One is the main circuit which will be mounted on the blind man s stick.
Smart blind stick using arduino circuit diagram.
I used an ultrasonic sensor with an arduino for detecting the obstacles.
This arduino smart blind stick project requires two separate circuits.
It cost me just 10 to make one.
The circuit diagram and pcb design are given below.
This arduino smart blind stick project requires two separate circuits.
You can see the wiring diagram from the above image.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.

Read arduino isp log.
Ultrasonic gnd to arduino gnd.
The cane can automatically detect an obstacle and give the user a feedback response by vibrating the walking stick and giving a warning sound.
Smart blind stick project using arduino and sensors.
The main board s circuit diagram is shown below.
The same circuit prototype can be made using a breadboard or zero pcb.
A buzzer is connected between d9 pin of arduino and gnd pin.
The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic.
Ultrasonic vcc to arduino 5v.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
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.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Blind walking stick arduino ultrasonic sensor.

One is the main circuit which will be mounted on the blind man s stick.
Now it is time for wiring the arduino.
That was the simplest way to make a smart stick for blind people using arduino.
To design blind walking stick using arduino ultrasonic sensor hc sr04 make the following connections as shown in the connection diagram below.
It is pretty easy does not have complicated wiring.
