ARDUINO WIRELESS LED DISPLAY BANNER(24X6 LED DISPLAY)

This is a instructables for creating the wireless led matrix display..
Today's life is all about the digital banners about the advertisement .when we a board with its scrolling text we think how difficult it could be to make that display but believe me its not hat hard its just a need of a cheap microcontroller and a lots of led on that with shift register and a counter ic

Step 1: WATCH THE VIDEO

Step 2: THINGS NEEDED

To make the wireless led matrix display you need the following things

1.ARDUINO UNO(OR CLONE)

2.BLUETOOTH MODULE(HC05,HC05)

3.74HC595 SHIFT REGISTER (3NOS)

4.4017 COUNTER

5.LED(144)

6.PCB(COPPER DOTS)

7.SOLDERING IRON

8.SOLDER LEAD

9.MALE TO MALE CONNECTING WIRES

10.SOLDERING SKILLS

Step 3: MAKING THE LED MATRIX

To make the led matrix follow these steps carefully

1)insert the first led to the pcb and solder the legs of thed then complete the one single row of the matrix

2)now bend the negative leg of the first led as in the diagram

3)repeat the same process of bending the negative leg of all the led for the row 1

4)solder all the negative legs together as shown in the diagram

5)repeat the same process for the 6 rows of the matrix

6)now comming back to the positive side bend the positive legs slight above the ground layer which is exactly perpendicular to the rows as shown in the daigram.

7)repeat the same procee of the soldering madness for all the 24 columns of the matrix

8)after that is being done solder a 100 ohm resistor to the columns

and you are ready to go with the led matrix

Step 4: MAKING THE DRIVER BOARD

From the following schematic we are about to make the driver board of the led matrix

just solder the parts on the pcb as per the schematic

step by step process

1)solder the three 74hc595 ic holder in the place and then solder the clock ,data and latch pin of the all ics to the one socket

2)then solder the output pins together with the male header pins

3)repeat the same for the 4017 counter as shown in the diagrams

4)solder the transistors and resistors as the schmatic and make a port for the rows

5)solder the ic to the power lines

6)wire the driver board to arduino as well as the led matrix

thats all you will be ready with the driver board for the led matrix

Step 5: WIRELESS PART(BLUETOOTH MODULE)

you could use any bluetooth modue such as HC-05 or HC-06 for the wireless part

then make sure you follow the above schematic to make a shield for the bluetooth module because the bluetooth module cant take a 5v input as the RX pin

so we are creating a voltage divider for the RX pin of the bluetooth module

ARDUINO UNO BLUETOOTH

+5V------------------------>+5V

GND---------------------->GND

RX------------------------->TX

TX-------------------------->RX(with voltage divider)
