Context: Need help fixing logic flow / breadboard circuit for Traffic & Pedestrian Light System (Tinkercad)
Hi everyone, I'm working on a traffic light and pedestrian light simulation project in Tinkercad (using 555 timers, counter ICs, and logic gates like 74HC4017, 74HC32, 74HC08, 74HC86, etc.) and I've run into an issue getting the pedestrian button trigger to work correctly.
The Problem:
The section highlighted in the white circle is for the pedestrian lights, but when I press the push buttons, the circuit doesn't react.
Expected Behavior / Logic Flow
Trigger Condition:
Pressing any of the 4 push buttons should trigger a state change across all LEDs in the system.
Traffic Lights (Upper Module β N, S, E, W):
When a push button is pressed, the active traffic lights should first transition to Yellow, and then turn Red.
Pedestrian Lights (Circled Module):
Default State: Pedestrian lights should stay Red ("Don't Walk").
Triggered State: When a push button is pressed, the pedestrian light should switch to Green ("Walk") for 10 seconds.
Reset State:
After the 10-second timer elapses, the system should automatically revert to its normal traffic light sequence.
