Smart Blind Stick With Ultrasonic Sensor Instructables

The stick scans for obstacles people and when found it points a light in the same direction of the obstacle.

Smart blind stick with ultrasonic sensor instructables.

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. Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. 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.

It consists of a blind stick which is equipped with ultrasonic sensors and pager motors. Here we will make a smart stick for blind person by using arduino and ultrasonic sensor. 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. It cost me just 10 to make one.

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. Through this the blind person can aware about the obstacles in front of him. Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal. Smart blind stick project using arduino and sensors.

Additionally the pager motor vibrates if there is there is an obstacle that is approaching the blind person at relatively faster speed. Learn how to make smart blind stick with arduino arduino project. The smart stick is built on arduino pro mini. I used ultrasonic sensor for detecting the obstacles.
