Build a Code-Activated Servo Door Lock with Arduino Nano Kit

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

Your child builds a secret-code door lock that opens a servo when the right button sequence is pressed. It’s a hands-on project that turns conditional logic into a working security gadget—perfect for a bedroom diary drawer or a DIY puzzle box.

What You'll Build

A working servo-powered lock that reads a four-button combination. Press the correct sequence and a green LED flashes as the servo moves to unlock; a wrong entry triggers a red LED. Every part connects on a breadboard with easy jumper wires—no soldering needed—and the final model can be mounted onto any small container.

What You'll Learn

• Program conditional statements (if-else) to check button sequences
• Control a servo motor to open and close a lock mechanism
• Use digital input from push buttons and output to LEDs
• Debug and iterate a real-world electronics project step by step

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for students aged 10-12 exploring electronics as a hobby, or CBSE Class 6-8 learners diving into coding and circuits. Also fits ATL Tinkering Lab activities and beginner workshops in schools. If you’re helping a child move beyond block coding to real Arduino code, this kit provides a confidence-building first project.

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.
