This is the HC-SR04 ultrasonic ranging sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. There are only ...

The arduino code can be loaded into the arduino IDE by either downloading or cloning this repository and opening the .ino file in the arduino IDE. Often times the raspberry pi python examples require ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

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 ...

HC-SR04 Ultrasonic Sensor Overview . Before we go and understand how the ultrasonic distance sensor works, we will first learn what ultrasound is: ultrasound sound is a high-pitched wave, in which the ...

Arduino Uno is a microcontroller board that is used to perform various tasks in different circuits. It needs a Code in C language to operate. We are using the Arduino Uno board in this project but you ...

Everything always looks good on paper (and in its seller’s description), so I plugged my module into an Arduino Prototyping Shield for a quick/lazy evaluation using an Arduino Uno. If you have played ...
