Question

Please make additional adjustments to the C++ code. There is only one infrared LED. If the train is detected (and stops for a few seconds), the LED should be turned on. Otherwise, it should always stay off.

Expert Solution

Step 1: A brief look at the question given.

In the provided question, the user is requesting adjustments to the C++ code for a system with a single infrared LED and an infrared sensor. The desired behavior is as follows:

When the infrared sensor detects a train, the LED should be turned on.
After a train is detected, it should stop for a few seconds with the LED turned on.
If the sensor no longer detects a train, the LED should be turned off.
The LED should always remain off when there's no train detected.

In summary, the user is asking for C++ code that ensures the infrared LED is activated only when a train is detected and turned off when the train is no longer detected
