boscoe:
I have an Arduino Uno and all I want to do is make it count in binary and output this in 8 bits paralleled on it's output.

Here's a code snippet for sequentially outputting 4 bits (0 - 15) to get you started:

     for (i=0; i<16; i++){
      //Disable output
        digitalWrite(12,HIGH)
      //set up LSB first
        digitalWrite(8, i&1);
     //shift right = divide by 2
        digitalWrite(9, (i/2)&1);
     //shift right twice =divide by 4
        digitalWrite(10, (i/4)&1);
      //shift right four times =divide by 8 for MSB
        digitalWrite(11, (i/8) &1);
     //enable output
        digitalWrite(12,LOW)
    }
