Perancangan Lampu Lalu Lintas Dengan Led Bicolor Menggunakan Arduino

Abstract

The growth in the number of vehicles every year will have an impact on the number of vehicles on the road. Thus, road congestion will increasingly occur in big city areas. Traffic lights are one of the tools to prevent congestion at especially at road intersections by making motorists more orderly stop and walk according to the signal of the light on. The need for traffic lights will also increase along with the number of congestion points at road intersections. Conventional traffic lights use three sets of LED lights with each set of red, yellow and green lights. Along with the development of technology, a Bicolor LED lamp was created which has two basic colors, namely red and green. With these conditions, the author is interested in developing a traffic light system with a one-package light system using Bicolor LED lights using an Arduino UNO R3 mockup. One Bicolor LED used will have red, yellow, and green colors. In this development it is expected to produce a system that is cheaper in manufacture and operation.
