In the programming interface of EV3 class, you can find a programming block specially designed for infrared sensors. These programming blocks allow the user to control the behavior of the robot according to the feedback from the sensor, such as starting or stopping when an object is detected at a certain distance, following the remote control signal, etc.
In addition, EV3 classroom provides a wealth of educational resources and project examples, which can help learners better understand how to use infrared sensors for innovative robot design and programming.
