Arduino Smart Doorbell Kit for Kids - Visitor Logger & Tune
Arduino Smart Doorbell Kit Kit with Arduino Nano
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 walking to your door and being greeted by a cheerful melody while a screen instantly shows who came by and exactly when. This kit turns a simple idea into a working smart doorbell that senses motion, plays a custom tune, and logs visitor times with real-time clock precision. It's the perfect weekend project for a young maker who wants to see code, sensors, and everyday life come together.
What You'll Build
You will assemble a complete visitor alert system on a breadboard. The PIR sensor detects a person within 3-5 metres, the buzzer sounds a programmable tune, and the 16x2 LCD displays the exact date and time of the visit-all kept accurate by the DS3231 RTC, even when the board is unplugged. Every future visitor leaves a timestamp you can scroll through.
What You'll Learn
- Wiring sensors and displays to an Arduino Nano without soldering
- Using conditional logic and interrupts to respond to motion events
- Communicating with an I�C LCD backpack to show dynamic information
- Programming a piezo buzzer to play musical notes and melodies

Who This Kit Is For
This kit is designed for curious minds aged 10-12 who are taking their first steps in electronics and coding. It's perfect for CBSE ATL lab projects, school science exhibitions, and weekend STEM club activities. If your child has ever wondered how smart home gadgets work, this hands-on build answers that question with real components and real code.
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.
What if I get stuck during the build?
Scan the QR code to chat with the AI companion that knows this specific kit inside out, or drop us a message on WhatsApp for human help within hours.
Do I need any prior coding experience?
None at all. The companion provides pre-written code blocks and explains every line, so you learn as you go. The wiring is completely solderless on the breadboard.
Can I change the doorbell tune?
Yes-once you finish the base project, you can edit the melody notes in the Arduino IDE to play any song you like. The companion even suggests a few popular ones to try.
Is this kit suitable for a school science exhibition?
Absolutely. The live LCD timestamp and audible alert make it an engaging demonstration of embedded systems. Many students use it to showcase sensor integration and real-time data logging.
PIR sensor detects visitor, buzzer plays a tune and LCD shows time of visit - logs visitors with DS3231 RTC.
