Again I tried to follow the model that was successful in the class "application and programming 
  interface." I drew in Corel Draw paths and I drill my board in iModela. Until then everything was normal.
  
  
  It is true that the LED array board has many components and that it has much work. But I wanted to 
  start.
  
  
  
  In the Fab Lab Sevilla we did not have these components and asked to come in 24 hours. And I started 
  to make the board.
  When the board was finished I tried with the ISP and to my dismay it did not work. I tried every Tuesday 
  morning to discover errors in the board. Installing and uninstalling resistors, leds, etc.. It has been 
  impossible.
  
  My final job was to amend Schedule C to LED array, but I expect the board to properly perform and finish 
  well in practice.
  I have to say that after I made my board do we have changed the mill and the following boards are made 
  very well. So will a new board to check the difference.
  Plan B was to practice in Arduino. I received quick instructions Arduino Juan Carlos Venegas and I 
  installed everything needed on my computer. In my windows 7 did not work properly. So I migrated to 
  Ubuntu to continue my work.
