in this tutorial i am showing to u how to make  a 4*4*4 led cube
 this cube is controlled by a single atmega chip(arduino nano) that is i am not using any shift registers or any other ics
so lets make it

materials that u need to make cube

diffusing leds

diffuse them by rubbing their glass top with sandpaper.

u can clearly seen that difference

making the jig 

For this , you will need a thick cardboard or wood . Drill 5mm holes into it so that it forms a 4×4 cube pattern with equal distances between all holes.

preparing leds for soldering

the short leg of an LED is its Cathode (-ive pin) and the long leg is Anode (+ive pin). 

Now, using  pliers bend the cathode (short leg) at 90digree angle to the right and then again bend it upwards to make the shape as shown in the image below.

test all leds with multimeter before soldering
CIRCUIT DIAGRAM

circuit diagram

now lets start soldering
first put 4 leds in a row and solder positive leads(common positive)

repeat same for all four rows

connect this rows with single stranded wire

repeat same for 4 layers

now lets start the assembling of cube layers

place and solder first layer to common pcb

repeat same for all layers connect same negative pins to the next corresponding negative pins

connect cathode pins to corresponding arduino pins

LAYER 1 CONNECT TO ARDUINO PIN A0

LAYER 2 CONNECT TO ARDUINO PIN A1

LAYER 3 CONNECT TO ARDUINO PIN A2

LAYER 4 CONNECT TO ARDUINO PIN A3

COLUMN 1 TO ARDUINO PIN A4

COLUMN 2 TO ARDUINO PIN A5

COLUMN 3 TO ARDUINO PIN D0

COLUMN 4 TO ARDUINO PIN D1

COLUMN 5 TO ARDUINO PIN D2

COLUMN 6 TO ARDUINO PIN D3

COLUMN 7 TO ARDUINO PIN D4

COLUMN 8 TO ARDUINO PIN D5

COLUMN 9 TO ARDUINO PIN D6
