8x8 LED MATRIX DISPLAY | ARDUINO | BLUETOOTH CONTROL

In this tutorial i show how to build a 8 x 8 LED matrix using an Arduino .

DO COMMENT WHAT YOU THINK ABOUT THIS INSTRUCTABLE,SO THAT I CAN IMPROVE IN MY FURTHER INSTRUCTABLES

have a look at the video tutorial for a better understanding of the entire tutorial.

PARTS NEEDED:

☻LEDS( 64 PCs)

☻JUMPER WIRES

☻CARDBOARD PIECE(16 CM BY 16CM)

☻ARDUINO UNO

☻LAPTOP OR PC (FOR UPLOADING CODE TO ARDUINO

☻POWER SUPPLY ( I USED A POWER BANK TO SAVE BATTERIES)

PUT IN ALL THE 64 LEDs IN THE CARDBOARD PC AS SHOWN

FIRST SOLDER THE POSITIVE TERMINALS OF THE LEDS ROW WISE

NEXT BEND THE NEGATIVE TERMINALS A LITTLE BIT AND SOLDER THEM COLUMN WISE (AS SHOWN) ACCORDINGLY.

EDIT: JUST ADDED FEW EXTRA IMAGES TO UNDERSTAND THE SOLDERING PART A LITTLE BETTER

SOLDER 8 JUMPER WIRES IN THE ROWS AND 8 JUMPER WIRES IN THE COLUMN .

FINALLY POP THE CIRCUIT OUT OF THE CARDBOARD SHELL

CONNECT THE AURDUINO WITH THE LED MATRIX

CONNECT EACH OF THE COLUMN TO PIN 2,3,4,5,6,7,8,9 RESPECTIVELY

ALSO,CONNECT EACH OF THE ROW TO PIN 10,11,12,13,14,15,16,17 RESPECTIVELY.

FINALLY UPLOAD THE FINAL CODE TO THE AURDUINO THROUGH THE CONNECTING WIRE

To download the final code go to the below link :

CONNECT THE BLUETOOTH DEVICE HC-05 TO THE AURDUINO:

connect rx of bluetooth to tx of arduino

connect tx of bluetooth to rx of arduino

vcc to +5v

gnd to gnd

download arduino bluetooth controller from playstore

click on connect and select your bluetooth device .

congratulations!! you have a working led matrix display controlled via bluetooth
