FIGURE 2-3 Creating a new schematic.

Initially, the schematic document will be labeled “Untitled.” It is a good idea to save it by
selecting “File” and then “Save As” from the menu. Give it the name flasher.sch. You can
actually have more than one schematic and board file within the same project. However, this can lead

to confusion, and it is easier to just have one of each and give the files the same name as the project. I
like to use an uppercase initial letter for the project and lowercase for the files.
Do not create a board file yet. We will do that after you have designed the schematic.

Figure 2-4 shows the schematic window. As you can see, there are a bewildering number of
sometimes cryptic icons on the left. If you hover the mouse over them, you will get some indication of
what they do in the status area at the bottom of the window.
