Build Your Own Smart Mirror Clock with Arduino Uno, RTC, and Temperature Sensor

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 mirror that not only reflects you but also seamlessly displays the current time and room temperature right on its surface—that’s exactly what you’ll create with this smart mirror clock kit. The OLED display hides behind a one-way acrylic sheet, giving a sleek, futuristic finish that feels straight out of a smart home catalogue. Perfect for a desk, shelf, or wall, this project introduces you to real-time clocks, environmental sensing, and I2C communication in a single afternoon.

What You'll Build

You’ll assemble a self-contained smart mirror clock unit that reads accurate time from a DS3231 RTC module and measures temperature using a DHT22 sensor. The 0.96-inch OLED display, placed behind one-way acrylic (acrylic sheet not included), shows the time and temperature clearly while remaining invisible when the display is off. It’s a functional home gadget and a hands-on introduction to embedded electronics.

What You'll Learn

• Interfacing I2C devices such as an OLED display and a real-time clock with Arduino
• Reading temperature data from a DHT22 sensor and displaying it live
• Building circuits on a breadboard and using pull-up resistors for stable I2C lines
• Writing Arduino code to combine sensor data, time, and visual output on a tiny display

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This beginner-friendly kit is ideal for CBSE Class 11–12 students exploring Arduino in their curriculum or B.Tech ECE/EEE first-years looking for a quick hands-on project. It also fits perfectly into ATL Tinkering Lab sessions and hobbyist workstations where a smart home gadget adds immediate motivation. Even younger makers, with adult guidance, can complete the build and proudly place the finished mirror on their study table.

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.
