How to Make a LED Cube at Home

Amazing 3x3x3 LED CUBE using PIC16F877A microcontroller
Here we are going to design simple 3x3x3 LED CUBE and connect it to PIC16F877A to get different patterns.

COMPONENTS: PIC16F877A controller PIC KIT 3
BREADBOARD 1 220 ohm RESISTORS (9) 1K ohm RESISTORS(3) 27 LED(GREEN,RED and YELLOW) BC547 TRANSISTORS(3) (USED AS SWITCH) 9V BATTERY(1) SOME WIRES

Let's see how to make 3x3x3 led cube at home

Step 1:

JUST DRAW NINE POINTS WITH EQUAL SPACE  THEN MAKE HOLES LIKE BELOW IMAGE USING ANY THINGS LIKE STRONG PAPER OR PARCEL BOX ANY MATERIAL

Step 2:

MAKE SMALL CURVE ON LEDS NEGATIVE SIDE LIKE BELOW IMAGES

Step 3:

PLACE RED LED ON ALL NINE HOLES

Step 4:
CONNECT AND SOLDERING ALL LEDS POSITIVE SIDE

CONNECT ALL  3  LED PATTERN USING HARD WIRE OR OTHER

CONNECT 3LED PATTERN WITH BELOW THINGS ANY HARD WIRE
THIS 3 PINS CONNECTED TO PIC MICROCONTROLLER

CONNECT LED CUBE ON BOARD

SOLDERING ALL 9 NEGATIVE PINS OF LED AND 3 POSITIVE PINS OF LED

STEP 5:
SOLDERING WIRE WITH ALL PINS

CONNECT ALL COL PINS(C1,C2,C3,C4,C5,C6,C7,C8,C9) WITH BREADBOARD

CONNECT 220 OHM RESISTORS THROUGH COL PINS

BC547 TRANSISTOR

PIC16F877A 
RB0,RB1 AND RB2 CONNECTED TO BC547 TRANSISTOR BASE PINS THROUGH 1 K OHMS RESISTOR

CONNECT ALL COL PINS WITH PORT C AND PORT D

BATTERY CONNECTED TO ALL COLLECTOR PINS AND ALL EMITTER PINS CONNECTED TO GROUND

CONNECT  12V DC ADAPTER TO PIC BOARD

STEP 6:
