I just need to modify the number of sensors being used and the pin number right?

Hi,I am using 3 HC-SR04 sensors. I tried the sketch but it doesnt even print out anything. What should I do
Check your settings and sketch, as I'm 101% sure it works. Thousands have used it. Maybe you don't have the serial baud rate set correctly to match the sketch?
