Using this smart blind sticks, blind individuals can communicate with their
surrounding environment with ease. That's the objective of this article. 285 million individuals,
roughly there are 246 million people with limited eyesight and 39 million individuals who are
blind globally. If people pay attention to them, it's extremely likely that you'll see they need
assistance from others to walk. To get where one wants to go, one must ask for directions. 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.
