While @sublimeartistry is correct that you could recreate this circuit from the parts (you would need to find them all though as some of them are unfamiliar and thus are probably custom). This appears to be the breadboard view of a Fritzing sketch. If you can get the .fzz file that this image was created from it will have a schematic view (possibly not routed yet which you would have to do) to give you the schematic. If you have the sketch clicking on the breadboard tab on the top line will give you the view above and clicking on schematic (to the right of breadboard) will change you to schematic view which should have the schematic representation of the parts in use. If the schematic view hasn’t been finished you would need to drag the parts to the correct position and route the connections.
