hello,I am developing a project for my school assignment, but I am not sure how to make the connections. I made the connections this way, do you think it is correct?

In a word, no. I rotated the HC-SR04 in schematic then looked at the rats nest lines which indicate the echo pin connects to ground, and the ground connects to an IO pin which likely means the breadboard view is wired wrong. You should always route schematic view and check that the connections are going where you expect. That will turn up errors in breadboard as in this case.
