how to connect the LCD to the arduino board ?
simply connect  the below shown like the image....
this is the lcd connected in the 4-bit mode

this is the em-18 rfid module...here the how the pins are connected i shown here



how to connect this module to arduino board ....
1.simply vcc pin of the em-18 module is connected to the 5v of the arduino board because it will take the 5v supply...
2.gnd of the em-18 module is connected to the arduino module ground

3. tx pin of the em-18 module is connected to the arduino pin 2(by the NewSoftSerial library...)

Now a day arduino is very famous for doing the research from the home....
Here i also done the some projects related to arduino board(clone)....


This is the boards of the induino and its pin discription where  the exactly pins are connected.
for more details of this board she this web site www.potentiallabs.com

 the controller used in this board is the ATMEGA328....

how to start the programming on the induino board(clone of the arduino)?

First download the arduino ide...then open the new file...
//simple program to blink the led light...

int led1=13;//the led 1 is connected to the pin 13 of the atmega 328 so
void setup()
{
pinMode(led1,OUTPUT);
//here we are externally defining that the pin 13 is output port

}

void loop()
{
digitalWrite(led1,HIGH);//this is the cmd gives the led on state
delay(1000);
digitalWrite(led1,LOW);//this is the cmd gives the led off state
delay(1000);
}

HOW TO START THE PROGRAMMING ON THE ARM MICROCONTROLLERS FAMILY

Here you can find the some important stuff related to the embedded system domain.
How to start the embedded system basics on the embedded systems.



Here first we want to know basics of the micro controllers,Most popularly used micro controllers are
1.8051
2.PIC
3.ARM
4.AVR

WHAT IS THE MICRO CONTROLLER DO ?
>>Micro controllers simply controls the external pheripheral which you connected to controllers.
Also embedded appliances controls are done from the basic controllers like above i mentioned.

HOW TO KNOW THE CONTROLLERS PINS TO CONNECT WITH THE EXTERNAL DEVICES?
>>Each controller having its own port pin configurations, for knowing about the you should visit the datasheets of the controllers and external devices.
>>each controller is made with different architectures.

8051 micro controller related one of the pdf

HOW TO DO THE PROGRAMMING ON EVERY MICRO CONTROLLERS?
>>For doing the projects and any appliances controlling programs from the controllers not to required to read entire data sheets.But you should know about the contents of the data sheets and schematics of the microcontrollers.

So

first of all you download the datasheets of the controllers and pheripheral (related to microcontrollers and the external devices which you want to do the programming or connections.)

HOW TO START THE PROGRAMMING?
>>Do not spend much time to understand the examples code.Spend the time to understand the language concepts and API's(Application_programming_interface)

WHICH OF THE IDE's(MICROCONTROLLER RELATED SOFTWARES) ARE THE BETTER TO START PROGRAMMING?
>>there are so many softwares are there for doing the programming on the microcontrollers
for each micro controller having their own ide's and software so use them do the work.some of the i prefer like this
s.no               micro controller family                                     softwares and ide's
1.                   8051 micro controller family                             KEIL
2.                   pic family                                                        MPLAB  
3.                   Arm family                                                      linux orCode composer studio
4.                   avr family                                                        arduino  
5.                   MSP FAMILY                                               Code composer studio                        


some of the link i am providing to download the softwares
they are
1.8051
