Smart Blind Stick using Arduino 👨🦯🔔 I developed a Smart Blind Stick using Arduino and an Ultrasonic Sensor to help visually impaired people detect obstacles in front of them. 🔧 Components used: ...
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 ...
This project is an Arduino-based smart security and perimeter-guard prototype built using an Arduino Mega 2560. The system can be armed and disarmed using a 4x4 keypad, displays system status on a ...
TRIG = 11 # GPIO pin connected to Trig of Ultrasonic Sensor ECHO = 12 # GPIO pin connected to Echo of Ultrasonic Sensor BuzzerPin = 13 # GPIO pin connected to Buzzer ...
Recently, I worked on a beginner-friendly electronics project using an Arduino Uno: a simple alarm system built with an LED, push button, and buzzer. The system works by using a push button to ...
This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...
The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
This 13-year-old has developed guiding spectacles that can help visually and hearing-impaired people
Over the years, the disabled community too has reaped the benefits of the vast technological advancements that have been noted in almost every field. The simple support stick or the humble hearing aid ...
The value of a mirror is in its clarity. If the reflection is cast by [danicakostic17]’s Uncooperative Mirror though, you’ll find anything but. It’s described as a useless machine, because it appears ...
