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.
Smart blind stick with ultrasonic sensor instructables.
He has named this stick as smart blind stick.
Here we will make a smart stick for blind person by using arduino and ultrasonic sensor.
Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal.
It cost me just 10 to make one.
Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st.
Learn how to make smart blind stick with arduino arduino project.
This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick all the feedbacks will be given to the blind man through a buzzer.
Smart blind stick project using arduino and sensors.
It consists of a blind stick which is equipped with ultrasonic sensors and pager motors.
The stick scans for obstacles people and when found it points a light in the same direction of the obstacle.
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.
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.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
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.
I used ultrasonic sensor for detecting the obstacles.
