Instructables
Picture of 3x3x3 LED cube shield

What should be in your kit:
1 – PCB
27 – LED’s
2 – 6 Pins for Arduino
2 – 8 Pins for Arduino
3 – Resistors
1 – Foam Guide
1 – Small Wire
1 – Medium Wire
1 – Large Wire
You will need: Solder Iron, Solder, Wire Cutters, Wire Strippers, Safety Googles, Helping hands are always good (but not manditory) and a really GREAT ATTITUDE!!!
to by a kit go to http://lwjmstore.blogspot.com/ 

In the below pictures I will be switching between RED LED’s and GREEN LED’s. My mom made a GREEN one…some parts didn’t turn out so good. She did try – and she is a VERY beginner! Good Job Mom!
Have FUN!

Step 1: Information

Little Information first


LED’s: All LED’s 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 LED’s: I’ve tested every single LED. However if you’d like to test to make sure…here’s 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 not…you’ve 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 LED’s.

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

Hey there I am making a L.E.D Cube 3*3*3 as a nightlight without any proggramer and i dont want to hook up a resistor to every led so can you please tell me how many and what value i would need? Thanks in Advance..... Power Supply: 5V Foward Voltage: 3.2-3.4 20mA
Leonelf asimobot4 months ago
5V-3.4v=1.6v R=U/I=1.6V/20mA=1.6v/0.02A=80 Ohm. next standard resistor value would be 82.
hey joey. nice ibble. done this in the past... thought i'd give it another go. talk to you soon,

what is this supposed to do?

Which aruino is this compatable with cause im getting a arduino uno

Hey Joey! I didn't think to check to see if you are on instructables!
This is mars - you autographed one of your first boards for my daughter!

Anyhow - we've built your project a couple of times - and my little girl now loves what she calls "LED Sculptures"!

Thanks a bunch and keep up the great work!

Cheers!

excuse me but do you have the squematic for the pcb ??
lookwhatjoeysmaking (author)  redtraceur2 years ago
i have them on my computer but i cant post them today becous my mother is the one who knows how to post that kind of stuf im sory,but i can tell you that its just multiplexed ther is 3 gnds one for each layer and 9 + one fore each calom.
You, my young friend, are awesome.
thank you
thnks i think i can figure out keep the good work

if you want the pins to be straight solder one pin of each set and then attach it to the arduino

Can you help me please? i want to have LED lamps in serial

power supply 3V
forward voltage 3.2-3.4
20mA

How many leds can i light up with 3V? Do i need a resistor for that, a
You're using 3V to power LEDs that need 3.3V? In that case, none.

i dont now. im sory
