Everyone knows the famous leds cube. I did mine a while ago, but it was too large for the project board + arduino + cables. I want to show you how I made this box so comfortable for you to locate it anywhere.

Step 2: CUBE LED

The first thing is to take 8 LEDs and attach all the negatives making a frame. Then in the middle add the led # 9 and connect the negative to any point.
Repeat the procedure until you have 3 phases.

Step 3: CHASIS

●Cut 2 of 10cmx10cm plywood frame. Then open holes to insert the positive pins of the led cube.

●Cut 2 strips of 8cmx5cm plywood. Cut 2 strips of 10cmx5cm plywood to one of these cut a small space to be able to insert the usb cable.

●Join the upper base with the columns and leave the lower one with the free arduino for the moment.

●We put small screws to fasten the arduino to the base.

●Open 3 holes near the led cube. These are for the negatives of each stage.

Step 4: ELECTRONIC

●Put glue to the positive pins of the hub to hold it.
● Solder one cable to each pin.

I know it's hard. But do it with patience :)

●Glue the 3 transistors to one side.
Then we join each left pin of the transistor. And we left one long. (This is GND).
●Solder on each pin in the center of the transistor a resistance of 10k. And to these we solder a cable.

●Solder to the right pin individually a negative phase.

●Insert the 9 resistors into the arduino's digital pins. 1-9 and those of the resistors of the transistor 11-13.

●We cut the excess cable from the LED cube. And we weld it to every resistance.

●After welding all the cables we put some hot glue and tape to prevent short circuits.

● Introduce the USB cable and close the box very slowly.

●Use screws to secure the chassis, in case you ever need to reopen it.

Step 5: CODE

It remains to your freedom. You can use any internet code and modify the location of the pins.
