int max_ultrasonic_distance_cm = 400; // set the maximum measureable distance for the ultrasonic sensor to 400cm NewPing sonar(ULTRASONIC_TRIGGER, ULTRASONIC_ECHO ...

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 ...

A simple Arduino project that measures the distance between an object and an HC-SR04 ultrasonic sensor and displays the readings in real time on a laptop using the Arduino Serial Monitor. The HC-SR04 ...

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 ...

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 ...

🚀 Distance-Based Automation Using Ultrasonic Sensor & Arduino I recently worked on a mini project that demonstrates how simple sensors and microcontrollers can be used to build smart automation ...

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: ...

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 ...
