STARRY NIGHT INFINITY MIRROR

The Starry Night Infinity Mirror is an Arduino project using LED strips to create an endless starry sky effect. Perfect for beginners, it serves as a beautiful home decoration, a fun learning tool, or a unique gift for events.

Software Used

ARDUINO IDE

Hardware Used

ARDUINO NANO, LED STRIP

Platform Used

ARDUINO STARTER KIT

The Starry Night Infinity Mirror is a fun Arduino project where you create a captivating light display using LED strips. Placing the LEDs between two mirrors gives the illusion of lights stretching endlessly, like stars in the night sky. With an Arduino, you can program the LEDs to change colors and patterns, such as twinkling or smoothly shifting hues. The Starry Night Infinity Mirror project is ideal for beginners and electronics enthusiasts alike. Besides being a stunning home decoration, it offers a hands-on way to understand lights, mirrors, and basic coding. It also makes a distinctive gift or decor item for parties and special occasions, Starry Night Infinity Mirror project for school students

Components used in this project are:

  1. Arduino NANO with cable
  2. LED Strip
  3. Male to Male Jumper Wires x 3
