I was going to run a motor for about a time and then turn it of. the time i want to enter from the user by using 3x4 keypad. I am is doing good,but the problem is the keypad doesn't wait for me to enter the next key and moves to next instruction.
i wants a code with which it waits to get input from keypad and after entering 3 numbers it move to next instruction not before. please help me.
here is the code am being used


Count = 0
While count < 3
     Get the keypad input
      Save in key(count).   //array to save keys
      Increment count
End while loop
