Smart Doorbell Kit with Arduino Uno - Fun Visitor Alert with Tones & LCD

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

Imagine your child proudly announcing visitors with a custom doorbell that plays a unique tone for each family member and displays their name on a glowing LCD screen. This project transforms an ordinary button press into a learning adventure in coding and electronics, giving young makers the thrill of building something that works in the real world.

What You'll Build

A fully functional smart doorbell system where pressing one of three buttons triggers a distinct melody and shows a pre-set visitor name on the 16x2 LCD. It's a confidence-building project that turns a stack of components into a working gadget you can mount on your door, impressing friends and family with every ring.

What You'll Learn

• How to read button inputs with Arduino and debounce them for reliable triggering
• Generating different tones and melodies using a passive buzzer
• Interfacing an I2C backpack with a 16x2 LCD to display custom messages
• Writing conditional code to assign a unique name and tune to each button press
