Decentralized Traffic Light System

Implements a decentralized traffic light system using Micro:bit devices and the Kitronik STOP:bit module. Traffic lights operate in clusters and coordinate turns via radio communication, ensuring, responsive traffic control with car detection through RSSI.

Features

• Decentralized turn based control using token-passing protocol.
• Car detection via RSSI on unit listening.
• Auto/Manual modes.
• Manual triggers microbit to pass the token.
• Failsafe if token gets stuck.

System Overview

• Each traffic light has a unique ID (e.g., C1A, C1B, C1C).
• A token is passed among them in sequence.
• Only the unit with the token can turn the light green.
• The green light activates only if a car is detected nearby (via strong RSSI).
• Fast listening Turns allow for all the units to cicle in a short period.
