Step 1: Instal Eagle
The program has to be installed so that clicking on the start button will bring up a menu somewhat like the one below. Clicking on the icon labelled EAGLE 4.13 will start the program. If you have a different version, those digits might be different, of course.
I am sorry, I do not remember any details of installing it. Selecting the default choices offered during installation should be fine, because that is what I usually do.
Step 2: Eagle control panel
You see a list down the left edge of the window. Clicking on the + signs to the left of the text label will expand that entry. Click on the + next to the "Projects" line to expand it. I have made a new folder here for my projects, and that examples folder was supplied with the program.
The non-obvious thing is that here you have to right-click to bring up the menu to add items.
I am going to draw a diagram of my oscillator, so I shall add a schematic next.
Step 3: Make a new project
Step 4: Rename new project
Step 6: Make a new schematic
