Abstract:
There is no doubt that the automatic control system has made a great move step in control systems that is lets the scientists thinking to find an enhanced techniques for making a control operation easier .As a result of this work, the control by the electronic programmable devices layout can be used in most engineering and electronic applications. As an example of that, the parallel interface control .This types of control lets microcontrollers monitoring and controlling a great number of devices that are connected to it easily .Several companies are manufacturing a thousand of integrated circuits designed to be used with the microcontrollers .Hence the system will be suitable for different applications and guides to solve many problems. All these performance let us to go forward in the design of the electronic circuit.
