Build a Smart Doorbell with Custom Name Display — Beginner Arduino Project

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 a doorbell that announces visitors by name on a crisp LCD screen and sounds a cheerful buzzer. This kit transforms a simple button press into a personalized home automation project — perfect for kids, students, and first-time makers who want to see electronics come alive in their own home.

What You'll Build

A working digital doorbell system where each of three buttons triggers a unique message on a 16x2 LCD and activates an active buzzer. You can label buttons with family member names or funny greetings. The display stays on until the next press, making it practical for real home use or school demonstrations.

What You'll Learn

• Wiring a breadboard with Arduino Uno, buttons, buzzer, and I2C LCD backpack
• Using the LiquidCrystal_I2C library to control text display
• Reading digital inputs from tactile switches with pull-down resistors
• Writing Arduino code to match button presses to custom strings
