Sharpener Kit: Build a Timed Automatic Pencil Sharpener with Arduino Uno and DC Motor

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Watch a simple button press transform into a precise 3-second burst - exactly what you need to drive a gear-reduced sharpening drum. This kit turns that idea into a real circuit, introducing you to motor drivers, timing logic, and push-button inputs without any prior experience. Whether it's a classroom demo, a tinkering lab project, or just the thrill of making something useful, you'll build a smart sharpener that never overspins.

What You'll Build

You'll construct a push-button controlled automatic sharpener. Press the tactile button and the DC motor spins for a fixed 3-second window, turning a sharpening drum (you can repurpose a manual sharpener or attach a simple drum - the electronics are the core). Once you've laid out the breadboard and uploaded the code, you'll see how a real-world timing task works in robotics and automation.

What You'll Learn

• Interface a DC motor with the L298N driver and Arduino Uno
• Write Arduino code to trigger a timed output on a button press
• Use a 9V battery to power a motor circuit safely
• Read and debounce a tactile button to prevent false triggers

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Perfect for CBSE Class 6-10 students exploring automation through the ATL Tinkering Lab initiative, young hobbyists aged 5-15 tackling their first motor project, and even B.Tech ECE/EEE freshers who want a quick hands-on intro to motor drivers. If you're preparing for a Smart India Hackathon prototype or a school science exhibition demo, this kit gives you a reliable timed-action module you can later modify for conveyors, feeders, or custom dispensers.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
