Abstract: Many bridge systems have been presented but there are still some limitations in terms of the high cost. 0ne function and difficulty of use that is not satisfactorily reliable and cannot be developed. There are two portions in this system. They are toll gates control system and auto bridge plates system. Arduino Uno is also used to control the stepper motor to lift bridges plates and servo motors are used to control tollgates. Therefore, the aim of this research project was to design and develop a prototype for an auto bridge system. It has a user-friendly interface, scalable and reliable by using an integrated system of hardware and software. The hardware such as Arduino Uno, servo motors, stepper motors, variable registers and wires are utilized to develop the prototype of an auto bridge system.
