Use a sequence of code blocks to create a simple animation.
When you have completed the code, try some of these challenges:
1. Experiment with how long each light is shown for.
2. Drag more commands from the left hand side and make the orange light flash.
3. Try and find a video of a real traffic light – it is slightly more complex than the example. Drag more commands from the left hand side to make the real sequence.
4. Experiment!
