hi 
I am working on a robot run by Neurosky mindwave
right by on blink
left by two blink
forward meditation
backward attention
and i see this code from www.pantechsolutions.net
the code blink this

this code one blink only
and i want this code by two blink how????
*any information about this give me *
thank you
