How to make a LED cube with arduino?
This is my first Arduino project….LED Cube Construction
- Carefully solder the anodes of 9 LEDs together making an E shaped structure.
- Cut the unnecessary parts of the anode after soldering.
- Repeat the process producing 3 such layers.
- Solder the 3 layers together by soldering the cathodes of each pillar of LEDs together.
What are LED cubes?
The L3D Cube (3D LED Cube) is a three-dimensional array of LEDs, of size 8x8x8, that is able to display various animations and graphics with the help of a microprocessor.
Do the LEDs work in the 8x8x8 cube?
When building the 8x8x8 LED Cube, we tested each and every LED before using it in the cube. We also tested every LED after we finished soldering a layer. Some of the LEDs didn’t work after being soldered in place. We considered these things before making a single solder joint.
What is the size of the led cube array?
The cube array is made of 8×8 bytes. Since each byte is 8 bits, this gives us a buffer that is 8 voxels wide, 8 woxels high and 8 voxels deep (1 byte deep). The interrupt routine reads from the cube array at given intervals and displays the information on the LED cube. The effect functions writes the desired LED statuses to this array.
How does the led cube work?
The LED cube is made up of columns and layers. The cathode legs of every LED in a layer are soldered together. All the anode legs in one column are soldered together. Each of the 64 columns are connected to the controller board with a separate wire. Each column can be controlled individually.
How many anode Connections do I need for my led cube?
You now have a LED cube with 64 anode connections on the underside of the base. But you need to connect the ground layers too. Remember those 8 small holes you drilled in a previous step?
