Abstract: The control system of traffic lights takes an important role in providing the better arrangement and control the flow of traffic. A better strategy in controling the flow of traffic can increase the movement of vehicles with shorten time-traveler. The aims of this writing is to design and make devices controller traffic lights using fuzzy logic ( smart traffic light ) based mikrokontroler Atmega 8535.
The design of the equipment used governance system traffic light intersection of two phases which meant there would be two cross a flaming green light the at same time. The stage design started from design hardware referried to blok diagram system, next the program was made in accordance with planning.  HC-SR04 sensors were used to detect passing vehicles on each cross. The sensors is using to detect the density of vehicles with 5 circumstances, namely a little, middle, normal, many and very much. The minimum time for green and red lights on each cross was 5 seconds, and maximal 30 seconds.
The results of testing of this devices showed the LEDs and seven segment displayed would light up according to the input sensor. Ability HC-SR04 sensors detected object at a distance 30-40 cm with error < 3 % without regarder light or color object. Thus, overall traffic light management system could adjust the flame of the old green light according to the level of the existed vehicle density.
