Simple distance measurement project using an HC-SR04 (or compatible) ultrasonic sensor with the Arduino Uno R4 WiFi board. The sketch reads distance and prints it to the serial monitor.

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 implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...

This project demonstrates a low-cost intelligent traffic signal system using Arduino and ultrasonic sensors to reduce congestion caused by fixed-timer traffic lights. Four HC-SR04 sensors detect ...

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 ...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle-avoidance and distance-measurement systems. The ultrasonic range finder measures the ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil was left in ...

If you’re going outside (only for essential grocery runs, we hope) and you’re having trouble measuring the whole six feet apart from other people deal by eye, then [Guido Bonelli] has a solution for ...

Abstract: Target/object detection, recognition, position, movement speed, etc. is easy when the object is near or easily visible. But, the same doesn't stand true especially when the object is far or ...
