1. os recommend? need simple run code, no gui required, i'm gonna write code on pc , transfer pi compile & run
2. gpio c++ library recommend?
3. i've been searching while , found few tutorials on how use motors, fans , not, motors go forward, backward , stop - need motor can control speed, same goes fan - there tutorials this?
