I only have a basic understanding of how to construct a circuit,

In that case you REALLY NEED to build some simple circuits first.
Remember the organisation of components on the schematic is NO INDICATION of the physical layout. Here is something you could try - at a pinch you can use an LED instead of a photodiode

As your op amps are 4 in a package you will need to use different pin numbers - so eg
Vcc+ (5V) pin 4: Vcc- (gnd) pin 11. all others same.

And I suggest reading this that may give you a better understanding of how shematics represent circuits

How to make a schematic you can post.

When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th…
