✨ A traffic light system simulation for a four-way intersection using PIC16F887 microcontroller.
Supports 3 flexible operating modes: automatic, manual control, and night warning.
Overview • Project Structure • How to Use • Features • Real Product
This is a traffic light system simulation for a four-way intersection using PIC16F887 microcontroller. The system supports 3 flexible operating modes that can be selected using buttons or switches.
Each mode accurately simulates how real traffic lights work:
- Mode 1 - Automatic: Red, yellow, and green lights cycle in sequence.
- Mode 2 - Manual Control: Users press buttons to turn lights on and off manually.
- Mode 3 - Night Warning: All 4 yellow lights blink continuously as a warning.

| Mode | Description |
| -------------------- | -------------------------------------------------------------------------- |
| 1 - Automatic | Lights cycle through: red → green → yellow. Each has a preset time. |
| 2 - Manual Control | All lights are off. Users press individual buttons to turn lights on/off. |
| 3 - Night Warning | All 4 yellow lights in all directions blink continuously. |- PCB
