OK, to make things clear I shall explain everything I want to do because I
cant seem to find anything that helps,

 I want to control a bionic arm.
 one motor for the shoulder
 one motor on the elbow
 1 motor for the wrist
 and maybe 2 or one servo for fingers,

shoulder motor 2 directions
elbow motor 1 direction
wrist motor 1 direction
fingers servo motor 1 direction

I will be using the Emotiv EPOC headset and the Arduino Uno(if you guys know any
better choices then plz tell me)

so now that everyone knows exactly what I want to do...can I please get info on
how to do what I want to do based on the info that I wrote?and based on my
info if codes can be made then that'll be great.

BTW this will be running with the Emotiv EPOC headset
