Project 42 - Potentiometer Fan "K-12 JUNO STEM KIT"


K-12 JUNO STEM KIT


What You Can Build Using K-12 JUNO STEM KIT

The "Potentiometer Motor" project lets learners control the speed of a fan (motor) using a potentiometer. By rotating the potentiometer’s knob, you can increase or decrease the fan speed, just like the controls in a real ceiling fan or variable-speed device


What You Can Learn

  • Variable Resistance: Understand how a potentiometer acts as an adjustable resistor, controlling the flow of electricity in a circuit.

  • Speed Control: Learn the principle of fan and motor speed adjustment using changes in resistance.

  • Analog Circuits: Discover the basics of analog (non-digital) control in electronics.


Real Life Problem Solving

  • Appliance Controls: See how variable resistors are used in everyday items—fans, dimmer lights, and audio equipment for precise settings.

  • Energy Efficiency: Adjust speed to save power, matching motor output to actual need.

  • User Comfort: Relates to customized comfort, safety, and practical usability in home and commercial appliances.

Applications and Extensions

  • Add a display to show speed or intensity visually as you adjust.

  • Experiment with different loads (LEDs, buzzers) and see how the potentiometer affects them.

  • Integrate with sensors for automatic speed adjustment based on environmental conditions.


Skills Developed

  • Working with potentiometers and motors in a dynamic control circuit.

  • Understanding real-world analog circuit behavior.

  • Practical hands-on troubleshooting for variable-speed electronics.


Real-Life Benefits

  • DIY Customization: Empowers learners to create adjustable gadgets for personal or scientific use.

  • STEM Integration: Connects real-world electronics to physics and engineering concepts.

  • Conservation Awareness: Reinforces efficient use of electricity through controlled output.


Why This Project Matters

The Potentiometer Motor project introduces a key principle in electronics—variable and analog control. It bridges the gap between theory and everyday utility, teaching learners how simple tweaks in resistance lead to major changes in electric devices.


Project 42: Potentiometer Motor gives students confidence and insight to innovate, customize, and optimize everyday technology!
