Introduction: Traffic Light Controller

About: 4D Makers is a group of curious engineers and enthusiasts who finds great satisfaction in creating and building anything from electronics.

Traffic lights are signalling devices positioned at road intersections,
pedestrian crossings, and other locations to control flows of traffic. It is a mechanical device consisting of a set of signal lights (Red, Yellow and Green) operating in a timed sequence, usually in seconds. In this project, the time for all the lights may be controlled by the user through the Controller module and be executed by the Receiver module. This project optimizes the capability of the 4Duino-24, a 2.4" colour TFT LCD display with resistive touch powered by the feature-rich 4D Systems Picaso Graphics Processor offering an array of display functionality and options, through connecting two modules wirelessly with the use of the ESP85266 Wi-Fi module.
