Скачать или смотреть (Hobbyist Project) Traffic Light and Pedestrian Signals (with Pelican Crossing Sequence) in Shed!

Here is a showcase of my traffic light, pedestrian signals and push button mounted onto my shed wall.

Using Arduino, I have tried to replicate the Pelican Crossing sequence seen on the public roads. The sequence is initiated by pressing the button. The traffic light and pedestrian signals are powered using 230V AC (the lights come with Transformers which step the voltage down to 12V) with Solid State Relays connected in series. The Solid State Relays are controlled by the Arduino.

Signal Heads Used (from left to right):
Monitron Mellor Pedestrian Signal
PEEK Elite (Halogen) Traffic Light
PEEK Elite (Halogen) Pedestrian Signal

(Also used here is a pushbutton manufactured by Monitron.)

The sequence is as follows:

1. Traffic light displays green, pedestrian signals display red.

2. When the button is pressed, the “wait” lamp illuminates.

3. After 30 seconds (maximum), the traffic light displays amber for 3 seconds, and the pedestrian signals remain red.

4. All lights display red for 3 seconds.

5. Pedestrians signals display the green man and bleeper sounds for 10 seconds.

6. For 2.5 seconds, the green man starts flashing and the traffic light stays red.

7. For 10 seconds, both the amber light and green man flash.

8. The pedestrian signals change back to red, while the amber light continues to flash for another 2.5 seconds.

9. Return to the beginning.
