3 x 3 x 3 LED Tutorial


This will be a step by step tutorial on how to create your own 3X3X3 LED cube from home.

Step 1

What do you need:

  • 1x Arduino Uno.
  • 27x LED's (i use 3 colors, 9 of each color)
  • 9x 220 ohm Resistors
  • 3x 22k Ohm Resistors
  • Soldering wire and rod
  • Jumper wires
  • Three 2N3904 npn transistors
  • perforated circuit board
  • Step 2

    Prepare the LED's

    Bend the negative terminal (cathode) of the LEDs and arrange them on the mold with the bent cathodes touching each other as shown in the photo. For those who do not know, the negative terminal is the shorter one

    Step 3

    Solder the LED Cube

    Ok So what is media?

    Media includes a lot of things but are usually images, text, audio, video and databases. When combined together this means media includes animations, movies, web series, TV, radio, games, books, podcasts, news articles, websites, instruction manuals and more.

    Media is basically everything we create, change, share, view and store. Digital media is everything we create, change, share, view and store using an App or website.

    What is a web site?

    A web site is a collection of web pages linked to a single name, such as google.com,or learncoach.com. This name is called a Domain Name and you can get one for each of your own web sites, usually for a small annual price.

    A web page is what you are viewing right now. A single digital media page designed to be viewed in an app called a web browser.
