An Australian-style pedestrian traffic signal
If you have ever thought what is missing in your life is a pedestrian traffic light, be sure to check out Ronald Diaz’s recent build.
The project uses a pair of lights that Diaz had in storage for the past decade, to which he’s finally added an Arduino controller that takes care of the walk/stop sequence.
The device is initiated by a pushbutton, which then cycles between a red light that implores pedestrians to wait, to a green signal that tells people to go, to a flashing red light and back to solid red. A piezo speaker was also included, which plays sounds based around actual Australian tones depending on the light state.
Code can be found over on GitHub, and you can see it demonstrated in the video below.
