This time you are going to extend the previous project to include a set of pedestrian lights and a pedestrian push button to request to cross the road. The Arduino will react when the button is pressed by changing the state of the lights to make the cars stop and allow the pedestrian to cross safely.
This is the first time you are going to interact with the Arduino and cause it to do something when you change the state of a button that the Arduino is watching. In this project, you will also learn how to create your own functions in code.
From now on, I will no longer list the breadboard and jumper wires in the parts required list. Note that you will always need these basic components.
