Arduino Led Cube 3x3x3

In this project, we are going to build a 3x3x3LED cube and connect it to the Arduino UNO to get the different patterns of light. For beginners, we will start with a simple pattern. A typical 3x3x3 LED cube that is connected to the Arduino UNO is shown in the images the cube consists of 27 light-emitting diodes, these 27 light-emitting diodes are arranged in a row and column-wise. so many cubes that can be designed, the simplest way of making is a 3x3x3 LED cube.

Advantage of 3 into 3 into 3 LED cube

There are some advantages to designing the 3 into 3 into Arduino LED cube.

  • The first one for this cube you don’t need to worry about the power consumption for dissipation.
  • For proper working low power supply is needed.
  • Here we won’t need to use any switching electronics for this cube.
  • With lesser logic terminals we don’t need to shift resistors or anything like that.

The LED uses about 20 milliamps of current the load consumption is much less than the number provided by the maximum current allowed through the LED. Normally LED works well from 2 milliamps to 5 milliamps anything higher than the current LED will be burned out.

Components required for LED cube

  • Arduino UNO or Arduino nano
  • The resistor and 27 LEDs.
  • Connecting wires.

Building construction of Arduino LED cube

In the first step, you need to check all the 27 LEDs are working properly once the cube is done if there is any faulty LED present in the cube it would be very difficult to replace so be careful to do this step.

The second step takes a breadboard wire and peels the area of the conductor. we can use any wires but breadboard connecting wires work great. after the peeling of this conducting wire. this wire is used for bridging the LED lights we will get to this point shortly.

Take 27 LEDs place them in a series manner and connect all the negative terminals. In this way connect the two pairs of LEDs and take a common negative.

After soldering all these connections you will get tree common negative inputs and 9 positive inputs to the LED cube. connect LED negative and positive connections through the resistors. and properly attach this connection to the Arduino board.

Upload the given code to the Arduino board. And enjoy the working of the LED cube.

The working video is given below this article if any doubt you can check the working video and the working tutorial thank you.
