Description
The LED Traffic Light Signal Module is a compact and easy-to-use component designed to replicate a real traffic signal system. It includes three high-brightness LEDs (Red, Yellow, Green) mounted on a single board, making it ideal for learning, prototyping, and automation projects.
This module is widely used in STEM education, smart city simulations, and embedded system projects, helping students understand sequencing, timing, and control logic in a practical way.
Key Features
- 3-in-1 LED Module – Red, Yellow, and Green LEDs
- Bright Output – High visibility LEDs
- Independent Control – Each LED can be controlled separately
- Easy Interfacing – Direct connection to GPIO pins
- Compact Design – Clean and organized layout
- Low Power Consumption
- Beginner-Friendly – Ideal for learning programming logic
Technical Specifications
- LED Colors: Red, Yellow, Green
- Operating Voltage: 3.3V – 5V
- Interface: Digital GPIO
- Pin Configuration: Typically 4 pins (GND + 3 control pins)
- Mount Type: PCB module with header pins
- Built-in Resistors: Yes (in most modules)
How It Works
Each LED is controlled independently:
- Red LED → Stop signal
- Yellow LED → Wait/transition signal
- Green LED → Go signal
By programming timed sequences, you can simulate real traffic light behavior.
Applications
- Traffic light simulation projects
- Smart city and IoT systems
- Arduino beginner projects
- Embedded system learning
- Robotics signaling systems
- Educational demonstrations
