Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

Ultrasonic and Infrared Sensor with Arduino Uno ## Overview This project demonstrates how to use both an ultrasonic sensor and an infrared (IR) sensor with an Arduino Uno. The ultrasonic sensor is ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are ... the LCD ends up being the hardest part. An IR transmitter/receiver pair are ...
