Hello, I was wondering what the black box was in the middle, I think its could be a audio amplifier module, just a audio connector, or something else?
A picture is basically useless. Upload the sketch file (the .fzz file, upload is 7th icon from the left in the reply menu) and we can probably tell you. Or you can click on the part in the sketch and its title will appear in Inspector.

the picture is all i got, its from a lab slides, no .fzz is provided, and the part wasn’t specified. I was just wondering if it was recognizable.
With only a poor quality image it is impossible to tell. The top left image is identified as a speaker in a google image search, so it may be an audio amp (there are a couple in 5 pin 220s I think) but it impossible to tell unless someone has one.

If you are referring to the black box in the bottom breadboard, that is a stereo 3mm jack. The left and right (tip and ring) are connected together on the outside so the same signal. In the middle is ground (black wires).
My guess is that the arduino is hosting a small microphone shield.
