Blind Walking Stick using ESP32

This system was proposed as an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. Our proposed project 1st uses ultrasonic sensors to detect obstacles ahead using supersonic waves. The microcontroller then processes this information and calculates if the obstacle is close enough.  If the obstacle is shut the microcontroller sends a signal to sound a buzzer. It additionally detects and sounds a unique buzzer if it detects water and alerts the blind. GPS is integrated with a Microcontroller . If the care taker wants to know the location of that person , they can easily find out by using IoT Cloud.
