Theses LED cubes are actually easier to make than you might think. If you take it one step at a time this project is not that difficult. That being said I did not right the adruino code for this. There are many codes out there to make the lights light up differently. This cube is a 4x4x4 which means 64 leds total. basically you will have four rows. You will make one row at a time then connect all four rows. The bottom row of leds will have the 16 positive pins stick out down word, and each of these will have 4 leds soldered in the isle there in. All of the ground in each row are connected. Then each row gets connected to it's on ground. So you will have 16 wires coming from the cube for inputs. theses will go to the aurdino with a resister inbetween for each one. 16 resistors total. Then from the cube will be 4 seperate wires for the ground wires one for each row. 20 wires total coming from cube to the aurduino.
Step 1: Tools and Supplies:
needle nose pliers
piece of wood
Step 2: Soldering LED's
First start by soldering one led at a time.
I marked where I started the leds on my block of wood.
I found a template online for the distances, you want the distance so that the leds, legs overlap the next led.
start in top right corner hole. Fold over the ground(-) pin to the out side.
bend over the next leds ground pin and over lap the first led and solder.
Do this for the top row. then you want the ground pins going vertical towards the top row your just soldered.
Then you can add cross wires the other way to connect the grounds and add strength.
