This series circuit worked for me my first try and is a very simple example of this type of circuit.

This is also a series circuit but because I had used two different colored led light bulbs this one did not work with only one battery. I have to use two batteries to increase the volts used to 6 volts in order for this circuit to work. If it doesn’t work the first time make sure there are enough batteries to have the amount of volts needed to power the bulbs.

This circuit is a parallel circuit. I tried to make one more complicated than the two parallel lines that are there now but I could not get it to work even when I increased the number of batteries. I checked to make sure the positive and negative sides were in the correct place but it still would not work so I decided to just make two parallel lines and when I do that the circuit works with one battery. I would recommend starting simple and then continue to try more complex circuits.
