After installing the Eagle software,
and the libraries (from SparkFun, and Fab Academy)
now I can start using the software doing the 'simple led schema'

First we create a project, and then we start to do the Schematic
Here is my Schematic for the 'simple led schema'
We can test it with the ERC (Electrical Rule Check) when finished

Then we switch to the Board view
and we start to design the board
first we move the components to the Board...

and then we do the routing between components

In order to create a groundplane we have to draw a polygon around the Board

And then using the Ratsnest function, it will automaticaly create the groundplane

Here is my final Eagle Schematic
It includes the Button (switch) and the led+resistor schema
connections to VCC and GND are not optimized, I should have used the copy feature to simplify with several VCC and GND objects, next time I will do it :-)

Here is my final Eagle Board
I created 2 polygons (one for VCC, one for GND), in order to minimize the drilling job

After applying Ratsnest
and all layers displayed

After applying Ratsnest
and only top layer displayed

An example of interface will adding a component in Schematic view

My configuration: Libraries, Design Rules (including MySettings.dru which is my resulting settings, inspired from SeeedStudio dru)...

As a result, here is my PCB schema (.png export from Eagle)

Here is preview of path

I had to minimize width of 1 trace
because I got an error on Roland (that was not identify with the DRC in Eagle)

My friend Roland is milling ;-)
