What You Can Build Using K-12 JUNO STEM KIT

The "Potentiometer Motor Speed" project lets learners control the speed of a motor using a potentiometer. Twisting the potentiometer dial increases or decreases the motor’s speed, introducing variable resistance and analog control in motor circuits.

What You Can Learn

Variable Resistance: See how turning a potentiometer changes electrical resistance, affecting current flow to the motor.
Motor Speed Adjustment: Discover how simple analog controls can smoothly vary how fast a motor runs.
Analog Circuit Design: Practice hands-on wiring of potentiometers and motors for responsive outputs.

Real Life Problem Solving

Fan and Tool Controls: Variable speed is found in everyday items like fans, hand tools, and mixers.
Energy Conservation: Match motor speed to the real need, saving energy and reducing wear and tear.
User Comfort: Offers convenient, smooth, and safe ways to operate devices.

Applications and Extensions

Experiment with controlling other devices (LEDs, buzzers) using the same circuit.
Integrate feedback, such as meters or indicators for speed display.
Add safety features, like cut-offs if overloaded.

Skills Developed

Wiring potentiometers to motors for hands-on control.
Troubleshooting analog, variable-speed circuits.
STEM understanding of real-world motor applications.

Real-Life Benefits

Practical Automation: Enables personalized device operation for comfort and efficiency.
STEM Integration: Connects physics, engineering, and electronics for full-circle learning.
Innovation: Inspires creative engineering and product design skills.

Why This Project Matters

The Potentiometer Motor Speed project ties abstract electronics concepts to daily experiences, empowering students to build and customize their own adjustable devices.

Project 63: Potentiometer Motor Speed makes learning about analog control, energy efficiency, and hands-on engineering fun and achievable!
