An assistive technology project designed to enhance mobility for the visually impaired. This smart stick uses ultrasonic sensors to detect obstacles within a close range and provides haptic (vibration ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

In this project, I developed an innovative hardware solution utilizing an Arduino Uno board paired with an ultrasonic sensor to create a real-time object detection system. The primary objective was to ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

Explore how the integration of a standard ultrasonic sensor, a vibration motor, and one or two microcontrollers resulted in a functional enhancement for a mobility aid. The developed ultrasonic ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
