![]() ![]() It's cheap and easy to make without the need of much soldering. I used an ultrasonic sensor with an Arduino for detecting the obstacles. The cane can automatically detect an obstacle and give the user a feedback response by vibrating the walking stick and giving a warning sound. ![]() Using this Arduino smart cane, a visually impaired person can walk without anyone's help. I wanted it to be very cheap and easily replicable so even a child can easily make it from scratch in a couple of hours. It was that evening that I came up with the smart cane. I realized that I could use technology to assist people like him. I was able to help him, and at that moment that I had an epiphany. The working bias of this circuit is between 3.3V to 5V DC. Find Computer Products, Electromechanical, Electronic Design, Electronic Kits & Projects and more at. The piezo vibration also plays a role in electroceramics, with its own recommended. Active piezo buzzer 1 pc General We will learn how to connect vibration sensor module, active piezo buzzer to Arduino board and use it. When it feels vibration then output of this module goes to logic HIGH. piezo vibration sensor available at Jameco Electronics. One of these is present in a piezoelectric sensor for mechanical pressure. When there is no vibration this module gives logic LOW output. One day while I was out walking, I saw a blind person having a difficult time walking down a busy street. This sensor module produce logic states depends on vibration and external force applied on it. ![]() This Arduino smart cane can assist with walking alone in new environments by taking inputs through an obstacle sensor (ultrasonic sensor) and providing feedback to the person through haptics (a vibration motor). I wanted to make something to help the visually impaired, so I created an open-source Arduino project for a smart cane. ![]()
