The scenario
This flowchart models a typical Arduino traffic light controller that cycles through green, yellow, and red lights with fixed timings and optionally checks a pedestrian button to skip the red light wait.
What is in this drawing
Read the decisions behind it.
01
Whether pedestrian button is pressed determines if pedestrian light activates and red light duration.
Use when designing or documenting an Arduino-based traffic light system, especially with a pedestrian crossing feature.
