selecting a single bit from a 32-bit word

I've a simple question. I'm trying to send a 32-bit word serial on an AT89C1051U. I'm trying to use a for loop and send the LSB each time, and then shift to the right every iteration. This, in theory, would allow me to send each bit no problem. Here's the code I tried, but I kept getting array problems.

     for(n=0; n<32; n++)
     {
       p3 = y;
       y >>= 1;
     }
