LED Cube Using Arduino

Led cube is an example of 3 dimensional led project. Led cube is much more than a normal led project. In other led projects we get a 2D view of led lights. But in the case of a led cube we get a 3D view of led lights which looks much beautiful than a normal 2D view. In a led cube we placed the led in all the three axis (x axis, y axis and z axis) which gives it a shape of cube. We can also increase the shape and size of led cube according our need. You can easily make a Led Cube by using Arduino or without Arduino. But the usability of an Arduino based Led Cube is much better than a normal Led Cube. Read More >>

Components -

1. Arduino UNO
2. LED
3. Jumper Wire
4. 100 OHM Resistor
5. 5 Volt Power Supply

The first important thing is to design the structure of the cube. For this purpose we have to use five Led layer. In each layer there will be 25 led. All the led will be arranged in the form of a matrix. The Led matrix is a 5x5 matrix. There will be 5 Led in each row and column of the matrix. All the negative pins of the Led will be shorted together while the positive pins of the Led will be kept separated for further connection. By following the rule you have make five layers of Led. Now we have to connect the five layers together to provide the shape of a cube. Take the Led layers one by one and then put it one over another. Connect the positive pins of Led from different Led layers together. This connected positive pins will be act as a column of the led cube. Total 25 column will be present in a 5x5x5 led cube. This 25 column will be feed up by the positive supply. The five layers will be used for ground connection. Read More >>

Now you have to design the circuit of 5x5x5 Led cube. To design the circuit I used Arduino uno, 5 piece of 100 ohm resistor and jumper wire. At first I connect the wires in each of the led layers separately. Then I used the 100 ohm resistor and connect it with the wires to limit the current in a particular range. Then I connect all the wires with the ground supply.

After this we have to give the positive supply in each of the column of led cube. There are total 25 columns in 5x5x5 led cube. I cascaded two columns alternatively. Then I used the digital pins of Arduino uno to provide the power supply. There are total 14 digital pins in Arduino uno. I connected the jumper wires in the digital pins of Arduino uno. Then I connected the jumper wires with the columns of led cube. Now the circuit connection is finished. You can place the circuit just under the led cube. And then you can make a base using wooden board to cover the circuit. The base will also provide a good support to the led cube. Make sure the base is strong enough to hold the weight of the led cube. Read More >>

Now we have to do the coding for 5x5x5 led cube. I used the Arduino IDE software to write down the code in Arduino. Open the Arduino IDE software and write down the code for Led cube. You can also customize the code according to your need. If you want some different design in the led cube, then you can modify the code based on the design you want. After this you have to upload the code in Arduino. But before uploading the code in Arduino, you have to choose the correct port and board type. After selecting the correct port and board type, you have to upload the code in Arduino uno. Read More >>
