The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.
Smart blind stick with ultrasonic sensor instructables.
This arduino board is small enough to install on a regular stick and has buzzer ldr sensor ultrasonic sensor and a water detector sensor interfaced to it.
Through this the blind person can aware about the obstacles in front of him.
Ultrasonic sensor sends high frequency pulses these pulses reflects from object and takes as echo time between echo and trig is measured by the microcontroller or arduino which is.
Learn how to make smart blind stick with arduino arduino project.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
It cost me just 10 to make one.
The stick scans for obstacles people and when found it points a light in the same direction of the obstacle.
Additionally the pager motor vibrates if there is there is an obstacle that is approaching the blind person at relatively faster speed.
Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st.
He has named this stick as smart blind stick.
It consists of a blind stick which is equipped with ultrasonic sensors and pager motors.
Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal.
The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound.
The smart stick is built on arduino pro mini.
I used ultrasonic sensor for detecting the obstacles.
Ultrasonic blind walking stick as shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second is receiver or echo.
