How It Works

The included control circuit sequences power to the LEDs in a programmed order to simulate stop, caution, and go signals. Users connect the power supply, follow the wiring guide, and watch the automatic timing circuit cycle the lights. The low-voltage design makes the kit safe for supervised classroom use.

Assembly Tips and Best Practices

• Read the assembly guide fully before starting to ensure correct component placement.
• Double-check resistor values and LED polarity to prevent incorrect operation.
• Use the battery holder or regulated DC supply within the recommended 3V-5V range.
• Test connections before finalizing the build to speed up troubleshooting.

Ideal Uses

• Classroom demonstrations and STEM lessons
• School science fairs and electronics labs
• Model intersections and traffic system demonstrations
• Robotics projects that require simulated traffic control

Safety and Maintenance

• Operate within the specified voltage range to avoid damaging LEDs or circuits.
• Keep components dry and store parts in a static-safe container when not in use.
• Supervise younger students during assembly and power-up testing.
