Morning Alarm with LCD
Morning Alarm with LCD – Build a Programmable Wake-Up Timer Using Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Wake up to a device you made yourself. This kit lets you create a fully functional morning alarm that rings a buzzer exactly when you tell it to, with the current time and alarm settings clearly visible on a bright LCD screen. Push buttons let you adjust the hours and minutes, making it feel like a real product you can personalise every day. It’s the perfect project to start learning how everyday electronics work, with no soldering required.
What You'll Build
You'll assemble a digital alarm clock on a breadboard that displays time on a 16×2 character LCD. The DS3231 real‑time clock module keeps precise time even when the main power is off, and a loud active buzzer sounds at the alarm hour you set. Three tactile buttons let you set the current time, configure the alarm, and mute the buzzer. In just a few hours, you'll hold a working morning alarm you can place on your desk.
What You'll Learn
- How to read accurate time from a DS3231 RTC module using Arduino
- How to display text and numbers on a 16×2 LCD with an I2C backpack
- How to use multiple push buttons to adjust time and alarm values in code
- How to trigger a buzzer as a time-based alarm and handle user input

Who This Kit Is For
Young makers in India’s ATL Tinkering Labs, CBSE and ICSE students (classes 6–10) beginning with Arduino, and parent‑child teams looking for a weekend STEM activity. Also a natural fit for first‑year B.Tech ECE/EEE students who need a simple embedded systems demo, or participants in the Smart India Hackathon exploring IoT basics. If you can follow a story‑like guide, you can build this alarm.
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?
Open the AI companion from the QR code or reach us on WhatsApp — it understands every connection and line of code for this specific alarm project, and can walk you through any problem step by step.
Can I change the alarm sound or add a snooze?
Absolutely. The companion includes suggestions to modify the buzzer tone pattern and shows you how to extend the code for a snooze button with just a few extra lines.
Will the clock keep time if battery is removed?
The DS3231 module includes a backup coin cell holder. Once you insert a cell (not supplied), the clock runs even when Arduino power is off, so you never lose the time.
Do I need any coding experience?
None. The AI companion explains every command in plain language, and you only have to type what it shows you. Many 10‑year‑olds have built this kit in one sitting.
DS3231 RTC triggers a buzzer alarm at a set time. Time and alarm set via push buttons shown on LCD.
