This is my final code

/* This is Embed c code for using a adafruit motor shield. The shift Register used is 74HC595N 
 * Pin 4 or PD4 is connected to Master Reset(MR) and Shift Register Clock Input (SHcp) 
 * Pin 7 or PD7 is connected to Output Enable (OE) 
 * Pin 12 or PB4 is connected to Storage Register Clock Input (STcp)
 * Pin 8 or PB0 is connected to Serial data input(Ds)
