Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

This project demonstrates how to use an IR infrared sensor module with an Arduino Uno to detect the presence of objects. The IR sensor emits infrared radiation and detects reflected radiation from ...

This project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light that works on AC mains. Whenever a person enters the washroom, the light bulb (or ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Building a maze-solving robot is an intresting way to get into the world of robotics and autonomous systems. Imagine creating a small device that can intelligently navigate through complex mazes, ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

[Fernando] sent in a tip about a pet project he’s been working on. It’s an interesting take on a 3D scanner. He used a stepper motor to rotate the object being scanned, and an Arduino for control, but ...

Abstract: COVID-19 and its genetic mutations pose a challenge to the world and affect the economic system of countries. Recently, countries were forced to reduce restrictions on airports, universities ...
