Model Traffic Lights Circuit | 555 Timer Project #15

A tutorial on how to make a model traffic lights circuit using 2 555 timer IC's and a few other electronics components. This circuit turns ON green LED, keeps it ON for some time, then turns ON yellow LED for a moment and finally turns ON red LED for almost the same duration as the green LED. This cycle again starts from green LED.
Explanation of how this circuit works is also included in the video.
