The IR Obstacle Avoidance module is perfect for Arduino projects. They work as serial modules, meaning you only need a single pin from your Arduino to control a sensor. Now you can add as many IR sensors to your Arduino project as your Arduino has I/O pins! This is the perfect module for robot cars and other devices that require a low-cost distance sensor. This module includes both an Infrared (IR) light out and an IR sensor to pick up the reflection of the light in a specific direction. This makes it easy to build robot that has many sensors at different positions, each requiring only a single pin from your Arduino or other Microcontroller.
