I used an ultrasonic sensor with an arduino for detecting the obstacles.
Smart blind stick using arduino circuit diagram.
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.
One is the main circuit which will be mounted on the blind man s stick.
The whole project has been designed on eagle.
The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic.
Ultrasonic gnd to arduino gnd.
Circuit diagram picture courtesy.
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 main board s circuit diagram is shown below.
That was the simplest way to make a smart stick for blind people using arduino.
Now it is time for wiring the arduino.
Ultrasonic blind walking stick using arduino circuit diagram.
The same circuit prototype can be made using a breadboard or zero pcb.
Read arduino isp log.
You can see the wiring diagram from the above image.
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.
A buzzer is connected between d9 pin of arduino and gnd pin.
Smart blind stick project using arduino and sensors.
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.
Prototype of arduino based smart blind stick there are two circuits in the project remote switch and the smart stick.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
Using this arduino smart cane a visually impaired person can walk without anyone s help.
Here i will explain by parts.
It cost me just 10 to make one.
This arduino smart blind stick project requires two separate circuits.
