Traffic Lights

Next time you are in a car stuck at traffic lights, or out walking, have a think about the traffic lights – why they’re there and how they work. You could have a go at making some traffic lights in Scratch. The questions I have about traffic lights are in the picture below. Do you have any additional questions? If you can find out any answers please will you let me know by commenting on this post? Thanks!
