In class we are learning about breadboards.

When I tried to put my circuit together, the light bulb wouldn’t go on. IK tried everything. I redid the whole circuit but it still wouldnt go on. With Mr. Calvert’s help, we found out that there was a problem with the LED light.  I learned that the longer leg of the bulb is the positive side, called an anode. The negative side is called a cathode. Here is a picture of the LED light:

Then, all the lightbulbs lit up. But since the negative  and positive holes aren’t connected to the bulb, I had to use jumper cables to connect them.
