Note that the wires that power the outside square come in on the bottom layer and go through the frame (behind a part of the LED strip) to the top layer. The middle 4 pieces get their 5V from the outside square and their GND from the center square. In the sketch, you can see that there are three parts, the center square, the outside square, and the middle 4 pieces that are in between the two squares. In the parts where the green line runs next to a piece of LED strip, it means that it is running underneath the strip (The frame has space for these wires). If you follow the green line you can see the order in which the strip sections of 12 LEDs are connected with each other (they are numbered in order on the image). The other wire that goes in is the Data line, this is the line that sends data to all LEDs to specify the color of them. This is not just powering the strip on two ends, this is actually necessary to eliminate the need for more complex solder joints. Two pairs of 5V and GND, one to power the beginning of the LED strip (on the bottom layer) and one to power the end (on the top layer). The drawing above (which represents the cube) should give you an idea of how everything is soldered.ĥ Wires go through the hole into the cube. Sketch_:C:\Users\Henrique\Desktop\arduino-1.0.5-r2/ledcube.It is important to understand how the wires need to be soldered before actually soldering them since there is not a lot of space to work with.

I’ve “fixed” to problem by replacing these lines (48). It seems to be caused by a compiler change or something in the 1.5.8 version of the arduino IDE.

#Arduino led cubes how to#
If you like LED cubes, you may also like how to build an 8x8x8 LED cube using a DIY kit.
#Arduino led cubes software#
If everything is correct you should find an example in the Arduino software under File > Examples > LedCube > ledcube. Unzip it to the Arduino libraries folder.
#Arduino led cubes download#
Go to this page and download version 1.05 of the Arduino IDE for your operating system. IMPORTANT: You need to download an older version of the Arduino IDE in order to compile/upload the LedCube Library to your Arduino board. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! Arduino UNO – read Best Arduino Starter Kits.I’m sure you’ve already seen some similar projects to this one but you never took action and made your own. In this tutorial I’ll show how you can create your own LED Cube 3x3x3.
