In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

An IR sensor module, which is used to detect fan’s blade to calculate the rpm, is connected to interrupt 0 means D2 pin of Arduino. Here we have used a stepper motor driver namely L293N module. IN1, ...

The sensor emits IR radiation and detects the reflection from nearby objects. IR sensors are widely used in various applications, from obstacle detection in robotics to proximity sensing in ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

🚪 Welcome to the Bidirectional Counter Project Repository! This project demonstrates how to create a simple yet efficient bidirectional counter system using Arduino and IR sensors. The counter ...

The automatic light system, based on Arduino Uno and IR sensors is designed to automatically switch the washroom light on and off, operating on AC mains. Whenever a person enters the washroom, the ...
