Circuit Diagram Help

Hello! So I am attempting to build an acoustic levitator, but before I start, I want to make sure I fully understand the circuit diagram and what I will be doing.

I attached a photo of what I will be following below. At the bottom of the image, a diode is attached to the battery and to the Arduino board. However, towards the right, it seems as though the wire the diode is connected to branches off and connects to the breadboard, as well. I am very confused. Would I connect the diode to some jumper wires? Is there a such thing as a three-branch jumper wire?! The same thing happens to the black wire right above it.

It would be greatly appreciated it somebody could help me figure out what is going on. The tutorial to the project is here: Mini Acoustic Levitation .

Thanks!

That project has problems!

It thinks that a US range finder has two US transmitters (sic) clearly untrue!
