Hi i want to know how to use 8 of the digital i/o pins at the same time?

e.g. pins 1,2,3,4,5,6,7 and 8 has output value of
             1,0,1,0,0,1,0 and 1 (which will be keep changing)

how can i output this data [glow]simultaneously[/glow] without any delay between two output signals??

the command
int pin1 = 1 ;
pinMode(pin1, OUTPUT);
digitalWrite( pin1, HIGH);
will drive only one pin at a time. So how to drive multiple pins at the same time?

thanks in advance  :)


You should look at this.


depending on the pins you pick and your board you can affect 8 pins at once.
