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 ...
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 ...
I’m excited to share one of my early Arduino projects, Smart Goggle I built this as a small assistive device for visually impaired people. The first version used an Arduino, ultrasonic sensor, and ...
