Schematic

       -If you have been following my blog, you would know I'm an architect who has nothing to do with electronics at all. it took
me sometime at the beginning it took me a while to understand circuit basics
I started adding the components of the circuit one Schematic Layout on EAGLE software following HELLO board design   
 

                                             
           EAGLE the software, allows you to schematically connect the components you have before converting this to a board. the
assignment was to add a LED light and a switch to the HELLO design, a friend advised to add resistors before each of them
to control the flow of current

TIP if you are new to EAGLE there 
    are tutorials,  available on  you-tube  are
 helpful  and  easy.   also  during  working
connections might get confused as some
 of them don't have names so make sure
 to re-name and label them to notice
them easily

The board
 

When you convert the schematic design to a board, it will give you the board with proposal connections between the components you will
 then have to replace them with what's called "route" where current is supposed to flow
 in the beginning it will be chaotic, all the schematic lines are intersecting. You have to keep rearranging it so as not to have connections
crossing each others. Also to avoid having long connections
By clicking on the component the software highlights all it connections, so you get to connect them one by one. When you connect them the
schematic connection will disappear. REMEMBER if you did any mistakes while connecting you can always click on "rip up", select the
route and it will convert it back to a schematic connection
Also if any time you used the wrong component, you can right click on it and click replace pick the new one, it will replace it but with the
same connections the previous had, so that you don't have to do them all over again

      Saving & Editing
After that go ahead and save only the top layer of your design for the circuit and the dimension layer for the border as a PNG image then
start editing the outer boarder as you wish
for me i used Photoshop its easier, after i finished designed the outline i stroke the boundary with 60PX. Now its ready for the milling machine

  

ERROR make sure both
PNG'S have the same
(0,0,) coordinates
otherwise it prints will
shift

And
 out
of
no
where

i had to Redo all the milling again, so i had a chance so simplify some of the connections so as the outline,
honestly i don't know what happened to the milling machine BUT you have to live with it
