Stepper motor not working in Arduino 101
After reading the Stepper library and searching for several, I saw that in an example using an EDISON ( I want to thanks to Guimficus for posting his code here: https://communities.intel.com/thread/99133) they changed the pinMode of the GPIOS they were using in the setup function : 

pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);


And after adding that seems to work like it is supposed to work. 

Cheers!
