How I Built This Arduino Puzzle Gift Box – Full Tutorial (Keypad + Servo + QR Code Game)

In Part 1, I showed you how I gave my brother a mystery gift that only unlocks if he solves 5 puzzles hidden in Easter eggs.

In this video, I'm showing you exactly how I built it step-by-step using an Arduino UNO, a keypad, and a servo motor!

You'll learn how to:
✅ Wire the 4x4 keypad and servo to Arduino
✅ Program a custom 4-digit password system
✅ Lock/unlock the box based on code input
✅ Build the entire box with simple materials

💡 Want to turn this into a puzzle hunt too? Just add QR codes that reveal puzzles!
