When you add a new wait block that uses an ultrasonic sensor, the software specifies that you will plug that sensor into port 4. Will your program still work if you plug the sensor into a different port?

No. LEGO has assigned each sensor a specific port - these are clearly shown in the building instructions and in the software. In order for an ultrasonic sensor to function properly, it must be plugged into port 4.

Yes, but only if the ultrasonic sensor is the only sensor plugged in to the NXT.

Yes, as long as you modify the wait block to specify the port number that the ultrasonic sensor is actually connected to.

Yes. While the ultrasonic sensor needs to be plugged into port 4 while your code is downloaded, you may move it to another port as soon as downloading is complete.
