Project 33 - Button Traffic Light "K-12 JUNO STEM KIT"

What You Can Build Using K-12 JUNO STEM KIT

In the "Button Traffic Light" project, learners create a mini traffic light system using three push buttons connected to three LEDs—red, yellow, and green. Each button independently controls one light, simulating how real traffic lights operate at road intersections. Pressing the red button turns on the stop signal, yellow warns to slow down, and green indicates it’s safe to go.

What You Can Learn

• Input-Output Control: Learn how pressing a button as an input triggers an LED as the output.

• Basic Circuit Design: Explore how multiple circuits can share a common power source while functioning individually.

• Traffic Light Logic: Understand sequencing and control by manually simulating traffic operations using buttons.

Real Life Problem Solving

• Traffic Systems: This simple model demonstrates how automated systems like traffic lights function using layered control signals.

• Safety Regulation: Helps visualize how different lights communicate movement safety on roads—essential for understanding public infrastructure.

• Interactive Learning: Encourages logical sequencing and thinking about time intervals between stop, caution, and go signals.

Applications and Extensions

• Convert the manual push-button control into an automatic timer-based light cycle.

• Use sensors or microcontrollers to simulate smart traffic light operations.

• Replace LEDs with other loads (like buzzers) to indicate sound-based signals.

Skills Developed

• Circuit building fundamentals using switches, resistors, and LEDs.

• Logical sequencing and understanding real-world automation behavior.

• Analytical skills through designing, testing, and improving light control systems.

Real-Life Benefits

• Automation Awareness: Builds an understanding of the logic behind automated city systems like traffic and pedestrian signals.

• STEM Integration: Encourages blending coding, electronics, and mechanical thinking for future smart-city innovations.

• Visual Learning: Provides a tangible way to understand how circuit logic represents real-world control systems.

Why This Project Matters

The Button Traffic Light project transforms a simple LED and button circuit into a real-world learning model of traffic management systems. It teaches learners about control, safety, and automation—the foundational principles of modern engineering and city technology.

Project 33: Button Traffic Light empowers students to explore how simple electronics influence safety, communication, and smart system design in the real world.
