Inspiration
I have created designed and built an “Ultrasonic Visually challenged peoples Walking Stick” device which will help Visually challenged people to walk with ease independently.
What it does
Using this smart blind sticks, blind individuals can communicate with their surrounding environment with ease. The use of this blind stick allows for more certain walking. The hc - sr04 ultrasonic on this stick alerts the user by buzzing when it detects an object standing in front of them. The individual can now move around fearlessly. Further LDR sensors are employed in the stick to help the blind distinguish between day and night. The microcontroller (Arduino Uno R3) receives sensor signals, processes them, and outputs brief pulses to Arduino pins attached to buzzers. The only way to help them get through their problems and lead better lives will be through this device.
How we built it
Using hardware components like ultrasonic sensor, Buzzer,Microcontroller, Arduino Uno etc
Challenges we ran into
Problems faced in the hardware product like sensors burning Voltage calculation
Accomplishments that we're proud of
I have submitted this project in the international journal.
What we learned
I have learned about iot technology and how to make use of it using the Android app
What's next for Smart blind stick using ultrasonic sensor
I want to promote my product to this society and help visually impaired people
