Next, connect 3 wires to part 1, make sure to connect them on the Din side. Step 1: Since we need sections of 12 LEDs you should start by cutting the LED strip in 12 pieces of 12 LEDs each. Make sure to pay attention to the direction of the LED strip pieces! Placing one piece incorrect can give you a lot of trouble.

This is how I did this, if you have a better way, just use your own. I numbered the parts of the LED strip in the image above to explain everything better. I am going to divide this section into sub-steps to explain everything better. 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. 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.
