[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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 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 library (with example) is designed to be integrated in projects using ultrasonic proximity sensors. It was tested with HC-SR04 device but it should be usable with equivalent sensors which have a ...

This project demonstrates how to send WhatsApp notifications using an Arduino UNO R4 WiFi board with CircuitDigest Cloud's WhatsApp API. The system uses an ultrasonic sensor to detect proximity and ...

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects. In order to program your ...

Arduino is one of the best platforms for beginners to learn electronics, programming, robotics, and IoT. Its simple coding structure and easy-to-understand commands make it an excellent starting point ...
