DIY Smart Blind Stick using Arduino and Ultrasonic Sensor Circuit Diagram If the person looses the stick the person can use an rf remote so the stick starts beeping and the person can find it. One more important feature of the system is that the system allows the blind person to send out a sms message with his/her gps location to the caretaker/relatives/loved ones of the person in case of trouble or being lost. Features of the Smart Blind Stick. Ultrasonic Sensor: The blind stick uses an HC-SR04 ultrasonic sensor to send out ultrasonic waves, detecting obstacles in the immediate environment.; Water and Light Sensing: LDR Sensor 5MM photoresistor is used to detect water puddles and measure the light conditions in the room.; RF-based Remote: An RF Tx Rx with an encoder and decoder IC is incorporated to
In this project, we will build a Smart Blind Stick using the Op-Amp IC LM358 and an IR Sensor. Earlier we build a Smart Blind Stick using Arduino & Ultrasonic Sensor HC-SR04. The project worked very well. But today, we are going to do the same project without the use of any microcontroller.

Smart Blind Stick Using Arduino With Ultrasonic Sensor and IR ... Circuit Diagram
For a smart stick for blind people using Arduino Uno, the content typically involves integrating ultrasonic or infrared sensors for obstacle detection. The Arduino Uno serves as the central processing unit, receiving input from the sensors and implementing algorithms for obstacle avoidance.

Like this we have in use of many other technologies like GPS, GSM, radio frequency identification (RFID), laser for making efficient as well as reliable blind stick for blind and partial blind people [4]. The scope of this paper is to make one such blind stick which is cost effective, efficient, easy to use. Working on the Smart Blind Stick. The Smart Blind Stick scans the path in front of it with the help of an HC-SR04 Ultrasonic sensor. Whenever the sensor detects any object in its path the buzzer starts beeping and also at the same time the LED turns on. The blind person can hear the beeping of the buzzer and manage to change the way. Therefore, a better device can be constructed using ultrasonic sensors, Arduino uno and other devices. 4. CONCLUSIONS Blind people face a lot of difficulties while travelling from one place to another. With the intension to help the blind, their difficulties, advance smart blind stick is proposed.
