Design a traffic lights controller for a road intersection : The intersection is between a major and minor road ( 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 â use a piezo Arduino speaker)
The minor road has a car detection sensor (use a push button)
You are to document both design of the controller and the implementation
Other than high-level requirements, the details are up to you ( timing, how the speaker beeps â frequency, does it beep faster as the timing ends, etc, etc)
