PIC 18F series microcontroller is used for control of signals to a specific time using port lines. In this contest we choose the Bicolor LEDs with Red and Green. The colors of the signals are illuminated by programming in the microcontroller. The aim of this paper is to generate three colors on a single traffic light instead of using three different color traffic signal lights. The purpose of this design is to reduce the manufacture cost of the signal lights and to use a minimum number of ports in a microcontroller and cable lines to transmit the signals to the light source. This paper describes a new design for the traffic signals.
