 **Final Words**
+As the original tutorial related , the system's performance is not very good. Can be pointed:
+  * The Arduino cannot read accurately the counts of the rotational encoder after 10 seconds (even if the pendulum returns to the equilibrium position , after a while , this equilibrium position will not give 0 as angle , consequently the PD equation will calculate the necessary input in the proportional valve as something different than 5,1V ( voltage that makes no air flow in the valve
+  * The Arduino cannot modify 8 ports at the same time to send the binary input to the DAC , so the calculated value by the PD equation will not be the same as the value on the input of the proportional valve. (The best choice is to use a DAC with an I2C or SPI interface)
