arduino or rasberry pi ?
I am deeply interested in building CNC's,3D Printers,Quad Copter's.....
So a little research showed that we need arduino which would act like the control unit for this very purpose .
But i have also come across some people who use parallel ports to control the machine (the processing is done on a computer) ""PS:- I might be wrong"".
So if the parallel ports can indeed be used for all these without a arduino in between ,wouldn't it be better to get a
"rasberry pi" and "USB to parallel port converter "
The advantages i am seeing are:
more processing power
probably easily programmable
we can get a lot of modules like (wireless......) which is made especially for an arduino
