How can I hook up 2 ultrasonic modules to my Arduino ?

Hello ! :smiley:

This is my first post here and I'm quite new to all this electronic stuff ! :~

But anyway, overhere I have an Arduino UNO and 2 ultrasonic modules ( a receiver and a transmitter)

Here is what they look like

So I was wondering how could I possibly use them with Arduino ? :relaxed:
I looked up everywhere but I couldn't find a solution so I hope you'll help me !

Thanks ! :sweat_smile:

I have seen the schematic on the web, but cannot find it right now.
(it was the designers notes)
The cheapest way, i guess, is to buy a prebuilt one....
but here goes:
