Does your code even compile with the # before "void setup" ?
I didn't inlcude # in the code, I just posted that on this thread to show where my coding starts.
Are you sure you have send and rec wired correctly at the motor controller end, signal names can sometimes be misleading. The arduino pin 1 should wire to a input pin on the MC and the MC should have it's output pin wired to arduino pin 0. Check the MC documentation for what they mean by send and rec pins.
I did make sure to make sure my MC output was connected to my Arduino input.
