Question

Design a traffic light controller for a road intersection: The intersection is between a major and minor road (the major road traffic is to be prioritized). Pedestrian crosswalks have push buttons for activating pedestrian lights (2 buttons for each direction). Use a speaker for visually impaired pedestrians (one speaker is sufficient – use a piezo Arduino speaker). The minor road has a car detection sensor (use a push button). You are to document both the design of the controller and the implementation. Other than high-level requirements, the details are up to you (timing, how the speaker beeps – frequency, does it beep faster as the timing ends, etc, etc). Implementation due – Arduino code file(s).
