Serial connection between two Arduino UNO

Simple example of a connection between two Arduino UNO. Ther are two pushButton with an red LED each connected to the first arduino. When I press them the arduino serial.prints a message to the serial pins 1 and 0. The message is received from the second arduino that decides how to move the stepper motor, if I press forward the motor goes forward for 5 steps, If I press reverse the motor reverses 5 steps.
