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

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)

Step 6: ARDUINO CODE

use the following colde to upload on the arduino using the ARDUINO IDE

VU METER (Music Visualizer) #1 With Arduino

This is the part one of the music visualizer series and In the following tutorial we are going to make a music visualizer AKA the volume meter or the uv meter from an arduino mega . The build process is very simple and easy and the program of arduino is also not that hard. Step 1: Watch the Video Step 2: Parts List             The parts needed for this build are 1.ARDUINO MEGA 2.COPPER DOT PCB 3.BREAD BOARD 4.JUMPER WIRES 5.LED (RED ,BLUE ,GREEN) 6.TOOLS(SOLDERING IRON ,SOLDER WIRE) 7.AUDIO SPLITER WITH A JACK 8.HEADER PINS Step 3: Testing on Bread Board( 1.LED's and ARDUINO ) Start by inserting the led on the bread board with the negative leg of the led to a common ground rail of the bread board (led count =20) the positive leg of the led will be there at any empty rail of the bread board as shown in the video and following pictures Then connect the ground of the arduino to the common ground rail of the l...

ARDUINO IR REMOTE (USE YOUR OLD REMOTE TO CONTROLL HOME APPLIANCES)

In this project you can choose any remote or a TV remote which you are using and you will notice that some keys are useless for your tv for that you can use that keys for controlling the home appliences like powering your TV,FAN,LIGHTS etc... you need to follow the simple procedure from the video so that you can record hexa values for that particular key and put into the program of the arduino Step 1: WATCH THE VIDEO   Step 2: THINGS NEEDED           The things needed for the following project are 1.ARDUINO UNO OR CLONE 2.IR RECIVER 3.ANY OLD REMOTE 4.RELAY MODULE 5.JUMPER WIRES 6.ARDUINO IDE 7.SOME LED'S IF YOU WANT TO MAKE A RELAY MODULE BY YOURSELF YOU COULD NEED (OPTIONAL) 1.RELAY 2.BC547 TRANSISTOR 3. 1K OHM RESISTOR 4.COPPER DOT PCB Step 3: RECIVING THE IR CODE FROM REMOTE BUTTON   This is the test to recieve the hexadecimal code of the remote button 1.install the ir remote library form the fo...

VU METER (Part-2) Using LM-3914 & LM-3915

This is the second part of the music visualization series and in the video above i have shown how you can make a simple VU meter by using the ic called LM-3914 or LM-3915. The part 1 is basically about how you can make the simple and cool looking VU meter by using the arduino microcontroller link to that is given as and now we will see the step by step construction of the VU meter STEP 1: Watch the Video   STEP 2: PARTS LIST     To make this cool looking UV meter we need these following things 1.LM-3914 IC 2.Breadboard 3.Copper dot PCB 4.18 pin IC Holder 5.Resistor(1.2k & 4k ohm) 6.Potentiometer (1K ohm) & Knob 7.Audio jack 8.Dc jack 9.LED (6-Green & 2-Blue & 2-Red) 10.some connecting wires   TOOLS REQUIRED 1.soldering iron 2.wire cutter 3.soldering wire etc...
