In the below pictures I will be switching between RED LEDís and GREEN LEDís. My mom made a GREEN oneÖsome parts didnít turn out so good. She did try - and she is a VERY beginner! Good Job Mom!
Have FUN!

Step 1: Information

Little Information first


LEDís: All LEDís have a Positive (+) and a Negative (-) As you can see on the picture below. The Positive (+) is longer than the Negative (-) You will always be bending the Negative (-). The official term for the Negative is "Cathode" and for the Positive is "Anode" For these directions we will use short and long.



Testing your LEDís: Iíve tested every single LED. However if youíd like to test to make sureÖhereís how to do it. Take a Lithium battery, stick the LED with the long led on the side of the battery marked with a "+". Press the Leds against the battery. The light should turn on. If notÖyouíve got yourself a bad LED.



Guide Sheet: I used this as my template. If you ever get confused (easy to do) refer back to the guide sheet. This will tell you how to bend and placement of the LEDís.

Each circle has 2 dots. The one with the arrow is the Negative (-) and the one standing alone is the Positive (+). This shows you which way to bend your Negative (-) led

Step 2: Connecting your LED's

ALWAYS FOLD DOWN THE NEGATIVE (-)..SHORTER SIDE
1) Start with the center hole. Folding down Negative (-) on the right side.
2) Place the second LED in as shown. Solder them together. Donít worry about the end of the LED being too long. We will be trimming them.
3) Place the third LED in as shown. Solder them together.
Continue on until all 9 LEDís are soldered together.



Before cutting the extra wire. Take another look to make sure all your LEDís are going the correct way and you folded down the Negative (-) This is the time to catch a mistakeÖyou can always unsolder and fix it.
Using your wire cutters, cut off the extra wire. Mostly should be on the 4 corners.
You should have.. (3) 9 pin LEDís squares

Step 3: Solder all 3 levels together

Now the tricky part starts. Stacking them together.

Put one LED piece back into the foam. You can find something to slide in between as shown.



Put your 2nd layer on. You will be soldering the Positive (+) to the Positive (+) on the next layer as shown. You may need to bend the wires so they meet. *Please note that the picture above is showing how to stack the layers. It has not been soldered together. If you connect one Positive (+) to a Negative (-) your LED will not light up in the end.



Do the same with the 3rd layer. *Please note that the picture above is showing how to stack the layers. It has not been soldered together.


This is what you should have in the end. This is the one my mom didÖalittle crooked, but thatís ok. As long as all the soldering is good the LEDís will still shine.
Set your LED "Cube" off to the side. Letís work on the PCB.

Step 4: Resistor's and wire's

The Resistors come straight. You need to bend as shown. There is not (+) (-) to these, so you donít have to bend a correct wire. Just bend either one down.

Place each resistor into the board. Solder each in on the back of the PCB. There is no right or wrong way for these. I prefer to have mine going in the same direction.

3 Black Wires

You will need to take your Wire Strippers and strip off a bit at each end. You will be soldering the top and the bottom, so strip off enough to do so. You may also choose to strip off all the black. Either way is fine.

Place the wires in each hole starting with the smallest and working up to the tallest.
Small (1st hole) Medium (2nd hole) Large (3rd hole)
Solder on the backside.

Step 5: Cube onto the PCB

Letís put the Cube onto the PCB. This part is also tricky, just take your time. It will work in the end!

Picture is showing the wires in the correct hole.
You can flip the PCB over and you will notice that only one of the holes on back have a connection.
Take your time and get each wire into the correct hole. Itís kinda like a puzzle. Once youíve succeed in doing that, solder the wires in place on the back side. Then give yourself a pat on the back!

Step 6: Make the connection with your black wires and conecting the arduino pins

Look at your black wires. You need to solder each of them to the correct level. First look for the very first LED you but into the foam. Picture below. This is the wire you will solder to the Negative (-).
Solder your short black wire to the negative (-) LED.
Solder your medium black wire to the negative (-) LED on the second level.
Solder your long black wire to the negative (-) LED on the top level.
You may have some extra wire. I couldnít get my wire cutters into the cube - so I left mine alone.

then insert the arduino pins into the pcb and solder.
then your done with the soldering part.
