I would buy an analog ammeter just so you can be sure at all times the current going through.
Yeah, I saw a picture of your setup before. Which, by the way, is appropriately terrifying and I commend you for your bravery.
Here is what you do. Go to Radio Shack and get a couple of 9v battery cap things (I can't believe I don't know the name of the terminals that fit on a 9v, but I don't), they are really cheap. Take the battery OUT of your 300 in 1 kit unit. Now, take the black wire from one of the caps and twist it together with the red wire from the other cap. Put them on batteries. You now have one free black wire and one free red wire that are providing 18v from the two 9v batteries in series. stick those into the power rails you are using on your breadboard.
The other thing, if I can give you some random advice here, that I would do is order one of these from amazon. This is a 5ma panel meter and you can put it in series anywhere in your circuit and it will tell you all the time roughly how much current is flowing. It is cheap and has very little accuracy, but they are good enough for this application. There are other ways to get constant current readings from your unit, but this is the cheapest and easiest for what you are doing and your level of experience with electronics.
