°•Multicolour 3×3×3 LED Cube With Custom Animation

Hi to guys and girls.

In this instructable i going to show how to make 3×3 multi colour LED cube using aurdino & also included some animation effects. i used three colours of LED's. [RED, GREEN &WHITE]

°• LED x 27 (any colour)
°• NPN transistors x3 ( BC547 or 2N3904 or 2n2222)
°• Resistors x 9 (220 ohm)
°• Resistors x 3 (22 k ohm)
°• Aurdino x 1
°• PCB x 1

The first step is bend the negative terminal of the LED.

To construct the LED layers we need an platform. Take a piece of chart & thermocol. place chart above the thermocol. Then draw a square of 5x5 in chart make hole at all the edges.

place LED in the platform and solder all the negative terminal. likewise make all the three layers septatley.

To combine all three layer bend the edges of positive terminal of LED's and solder the first, second & third layer.

connect the 22 k ohm resistor in base connection from transistor

JUST COPY & PLACE THE BELOW CODE.

//glow all the lights in LED cube
voidsetup()
{
pinMode(2,OUTPUT);pinMode(3,OUTPUT);pinMode(4,OUTPUT);pinMode(5,OUTPUT);pinMode(6,OUTPUT);pinMode(7,OUTPUT);pinMode(8,OUTPUT);pinMode(9,OUTPUT);pinMode(10,OUTPUT);pinMode(11,OUTPUT);pinMode(12,OUTPUT);pinMode(13,OUTPUT);
}
voidloop()
{
//set pin 11-13 high so as to light all the layers
digitalWrite(11,HIGH);digitalWrite(12,HIGH);digitalWrite(13,HIGH);digitalWrite(6,HIGH);
//set the middle column ON throughout//light the other columns on andoff in a sequence
for(inti=2;i{
if(i==6)
{
}
else
{
digitalWrite(i,HIGH);
delay(100);
digitalWrite(i,HIGH);
}
}
}

digitalWrite(i,HIGH);
delay(100);
digitalWrite(i,HIGH);

you can see the code in the programme just change it by.

digitalWrite(i,HIGH);
delay(100);
digitalWrite(i,LOW);

it will make some animation effect

After the programme connect pins from cube to aurdino digital pin as per the circuit diagram.
