Step 1
First, you need to set up the NRF24L01 modules for communication between the nodes. Here's an example code for setting up the modules: ```cpp #include <SPI.h> #include <nRF24L01.h> #include <RF24.h> RF24 radio(9, 10); // CE, CSN pins const byte address[6] = Show more…

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).
