Do you remember the first time you tried to read a map? There were all those weird symbols and curving lines that you had to figure out before you could get anywhere. Electric circuits are kind of the same way… people use schematic diagrams to write down how their circuit is wired so others can build it, too.

Now that you’ve built a couple of the breadboard circuits, it’s time to figure out how to read the symbols and build a circuit from a diagram. At first, it may seem a bit overwhelming with all the strange symbols and lines drawn all over the page, but don’t worry – after a couple of circuits, you’ll be cruising through these like a pro.

The first thing you need to do is download the schematics (if you haven’t already) and then watch this video:
