Project 55 - Potentiometer LED Control "K-12 JUNO STEM KIT"

What You Can Build Using K-12 JUNO STEM KIT

The "Potentiometer LED" project empowers learners to control the brightness of an LED using a potentiometer. By adjusting the potentiometer, students can increase or decrease the LED’s intensity—demonstrating analog signal control in action.

What You Can Learn

• Variable Resistance: See how a potentiometer changes resistance in a circuit, affecting the amount of current running to the LED.

• LED Dimming: Explore how brightness is smoothly adjusted, just like in dimmer switches at home.

• Analog Control: Practice building circuits where outputs respond to real-time user inputs.

Real Life Problem Solving

• Lighting Control: Potentiometers are used in dimmers for lights in homes, theaters, and offices for comfort and energy savings.

• Device Adaptability: Learn how similar control circuits work in audio equipment, alarms, and many gadgets.

• STEM Integration: Connect electrical basics with hands-on control systems.

Applications and Extensions

• Use the potentiometer to control other devices like buzzers, motors, or displays.

• Add multiple LEDs for color mixing or advanced lighting effects.

• Integrate with light sensors for automated brightness adjustment.

Skills Developed

• Wiring potentiometers and LEDs for variable output.

• Troubleshooting analog LED control circuits.

• Creative thinking in user-centered electronics design.

Real-Life Benefits

• Personal Comfort: Supports adjustable lighting for convenience and well-being.

• Energy Saving: Using only the brightness you need helps conserve power.

• Practical STEM: Directly links theory of resistance and current with real-life applications..
