Traffic Light Kit

Description

The faithful traffic light is something that has been around since the first cars after drivers had difficulty in deciding who had right of way at a junction. The modern traffic light found in the UK is often connected to an intelligent network of controllers and logic to try and keep traffic moving as efficiently as possible. While this project is far more trivial, you will learn how to build a traffic light that uses the correct colour sequence found on many UK traffic lights! This circuit is based around a 555 astable oscillator as a clock source, a 4017 IC as the counter stage, and a diode matrix for creating the light patterns.
