The Smart Mirror Arduino project combines technology and everyday utility, transforming a conventional mirror into an interactive and informative display. This innovative project utilizes an Arduino board, a Liquid Crystal Display (LCD), a NeoPixel LED strip, and a microphone button to create a versatile Smart Mirror.
Upon startup, the mirror showcases a dynamic “Starting Up” message on the LCD while activating a captivating LED strip to mimic the boot-up experience.
The project allows users to input messages through a simulated app interface, displaying them on the mirror’s surface. The mirror intelligently handles longer messages by scrolling them for visibility.
Component List:
| Name | Quantity | Component |
|---|---|---|
| U1 | 1 | Arduino Uno R3 |
| LEDLED Strip | 1 | NeoPixel Strip 4 |
| PIEZOSpeaker PIEZOMicrophone | 2 | Piezo |
| UDisplay | 1 | LCD 16 x 2 |
| SMicrophone Button | 1 | Pushbutton |
| R1 | 1 | 220 Ω Resistor |
| R2 R3 R4 | 3 | 1 kΩ Resistor |
The Smart Mirror further simulates a microphone function through a button press, providing an interactive element. The microphone function prompts the mirror to display a “Microphone Active” status and awaits text input, offering a glimpse into voice-activated possibilities.
After receiving a message, the mirror sends a visually engaging LED notification and prints the message on the display, enhancing user interaction.
A simplified circuit involves connecting the Arduino board to the LCD, NeoPixel LED strip, and a microphone button. The LCD provides visual output, the NeoPixel LED strip adds dynamic lighting effects, and the microphone button simulates voice interaction.
Wiring and connections may vary based on specific components used, but this basic setup forms the foundation for a Smart Mirror that blends practicality with technology.
