4. Working Principle
The traffic light module operates based on digital signal control:
- Power Connection: The module connects to a power supply via GND and VCC ports, operating within 3.3V to 5V to ensure proper functionality.
- Signal Control: The signal pins (R, Y, G) receive input signals from a controller. A high-level signal activates the corresponding LED, while a low-level signal turns it off.
- Connection Configuration: The red anti-reverse connector and matching cable ensure safe and efficient connections, minimizing wiring errors.

5. Pin Description
| Pin Name | Description |
|----------|---------------------------------------------------|
| VCC | Positive power supply (3.3V to 5V input) |
| GND | Negative power supply connection |
| R | Control signal for the red LED |
| Y | Control signal for the yellow LED |
| G | Control signal for the green LED |

- VCC: Connects to the positive terminal of the power supply. Ensure the voltage remains within 3.3V–5V to prevent damage.
- GND: Connects to the negative terminal (ground) for stable operation.
- R (Red Signal Pin): Controls the red LED (high level activates it).
- Y (Yellow Signal Pin): Controls the yellow LED (high level activates it).
- G (Green Signal Pin): Controls the green LED (high level activates it).

6. Application Scenarios
The Keyes 2021 DIY Electronic Brick Traffic Light Module is widely used in:
- Education: Teaching traffic signal principles and conducting experiments to help students understand LED operation.
- DIY Projects: Creating traffic light models or other creative electronic projects.
- Experimentation: Demonstrating lighting control and signal display for analyzing multi-signal variations.
