Prototype of arduino based smart blind stick there are two circuits in the project remote switch and the smart stick.
Smart blind stick using arduino circuit diagram.
Now it is time for wiring the arduino.
Ultrasonic vcc to arduino 5v.
This arduino smart blind stick project requires two separate circuits.
One is the main circuit which will be mounted on the blind man s stick.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Ultrasonic gnd to arduino gnd.
Circuit diagram picture courtesy.
I used an ultrasonic sensor with an arduino for detecting the obstacles.
A buzzer is connected between d9 pin of arduino and gnd pin.
The whole project has been designed on eagle.
That was the simplest way to make a smart stick for blind people using arduino.
The remote switch is simply an rf transmitter circuit with a switch connected to the d3 pin of the encoder ic.
The main board s circuit diagram is shown below.
You can see the wiring diagram from the above image.
One is the main circuit which will be mounted on the blind man s stick.
Here i will explain by parts.
The circuit diagram and pcb design are given below.
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.
This arduino smart blind stick project requires two separate circuits.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
It cost me just 10 to make one.
Ultrasonic blind walking stick using arduino circuit diagram.
To design blind walking stick using arduino ultrasonic sensor hc sr04 make the following connections as shown in the connection diagram below.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
Read arduino isp log.
It is pretty easy does not have complicated wiring.
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 same circuit prototype can be made using a breadboard or zero pcb.
