		abstract={At this time being is very developed on institution system work like government, technology business, and education. One of the technology development affect to the government institution dealing with traffic system. One of the important things in traffic system is traffic light. The function of traffic light is to support and control the traffic system. However, sometimes traffic light can be a cause problem of traffic jam. It is happened because the conventional traffic light system that still works constantly all the day or not adaptive and flexible. Thus, to anticipate the situation it needs an adaptive traffict light that works based on the amounth of vehicles in every side of road. This device work based on the indication of the object along with adding time amounth of the green light and red light in phase 1 or phase 2. This prototype system uses microcontroller ATMega 8 as a master and slave, infra red sensor, and photodiode as object indication, LED and seven segment as a traffic light indicator and indicate the time of the lights, LCD 2x16 to preview the object and time allocation for every road. This system runs with Serial Peripheral Interface (SPI). From the overall testing system, it has worked well. It proof by the working system device that is used Serial Peripheral Interface (SPI) working system. It sends indicator light colour in traffic light and timer in every traffic light indicator from microcontroller master kit which is send to microcontroller slave. However, sensor that is expected can detect the pass object in radius ± 5cm cannot work well. Therefore, sensor is set in the 1 cm distance.
Key words: Traffic Light, Microcontroller Atmega 8, Infra red sensor and phtodiode, LED, Seven segment, LCD 2x16, SPI}
