* Since the oscilloscope readings were not very clear, we tried to understand what was wrong, and it took us two attempts to get it right. During the first attempt, the ground connection was not properly attached, and in the second, the channels were inverted.

* I used the code that Adrián Torres’ Fab Academy documentation provided as a reference for programming the distance sensor. But unfortunately it was not working.

* Gert passed by and suggested that I check the female-male cable connections, as a loose connection could be causing the sensor to malfunction.And indeed, after changing the cables, the sensor started working properly.
