Arduino basic:Learn every thing about arduino

Arduino Basic

Arduino is basically a micro-controller that is having the capability to control any type sensors,motors,receivers,controllers,modules,any thing.

Arduino board is having a micro-controller chip (or IC) installed in it ,which is responsible for sending and receiving different types of signals.The board is also having a small ROM and RAM in it.

so for controlling any sensor,motor, or any module ,You first need to write code in C language in the Arduino(IDE) application which can be downloaded from the web. 
 




The Arduino board works in the Binary language that is 0 or 1,HIGH or LOW, TRUE or FALSE.So after writing the code in Arduino application you need to connect the arduino board to PC ad then press the upload button ,then you will  see in the application below writing compiling ,which means that before uploading the code ,Application converts the C language written code to Machine Level language, that is Binary and then uploads it to the board.

Arduino board comes in many variants like Arduino uno,mega,leonard,mini etc


Now the most important part is the coding:-

HOW TO CODE:-

Coding an Arduino is very much easy,in fact it is the easiest part if you now the C language. 

First thing: In the arduino application you will there are two thing written, Void setup and Void Loop. 
Void - The void keyword is used only in function declarations. It indicates that the function is expected to return no information to the function from which it was called.
Setup- You need to declare the INPUT and OUTPUT of the PINs, and any code written in the void setup will run only once.
 void Loop- Any code or program written in this field will run endlessly untill the power is connected to arduino.


Second : You can declare any variable name to a PIN and all the code writte i the void setup a void loop will be enclosed within {  } brackets .

Let's start the coding:-

1.First you need to declare any variable name to PIN no's, this thing will be written above the void setup
 like this 

int LED=13;
int Buzzer=9;
Here a variable named LED is created that is connected to pin no 13 of the arduino pin
 now you need to specify the in and output of the variable in void setup like this

void setup()
{

pinMode(LED,OUTPUT);
pinMode(Buzzer,OUTPUT);

}

After need to specify the working of it in the void loop like this

void loop()
{

digitalwrite(LED,HIGH);
digitalwrite(Buzzer,HIGH);
delay(2000);
digitalwrite(LED,LOW);
digitalwrite(Buzzer,LOW);
delay(2000);

}

here the led will glow for 2 seconds then it will stop for 2 Seconds ,this process repeats endlessly.

delay mease that arduino will not send any output signal or receive any input signal ie it will stop for the specied time and (1000) means 1 second,and digita write mease arduino will send a signal to the specied pin.it can be HIGH or LOW. 

You can also run and check the working of this code ,(written below) just copy and paste the code to the arduino application and upload it.


//this code is written by Sameer verma

int LED=13; //connect led to the pin 13 of arduino
int Buzzer=9;

void setup()
{

pinMode(LED,OUTPUT);
pinMode(Buzzer,OUTPUT);

}

void loop()
{

digitalwrite(LED,HIGH);
digitalwrite(Buzzer,HIGH);
delay(2000);
digitalwrite(LED,LOW);
digitalwrite(Buzzer,LOW);
delay(2000);

}

Arduino:How to program an arduino using loop statements

Image
Programming  an Arduino(Level 2) using loop statements   1.Conditional statements(if/else) These statements are executed when the condition which is specified in it becomes true And these statement's are used when when we need to perform a specific task after the condition becomes true ,we can write this statement if the void loop field like this if(condition) { (Task which need to be performed goes here) } else { (If the condition becomes false then this block of code will be executed) } Example of code if ( x > 120 ) digitalWrite (LEDpin, HIGH ); if (x > 120 ) digitalWrite (LEDpin, HIGH ); if (x > 120 ){ digitalWrite (LEDpin, HIGH ); } if (x > 120 ){ digitalWrite (LEDpin1, HIGH ); digitalWrite (LEDpin2, HIGH ); } 2.While loop(while) A  while  loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Something must change the tested varia

Automatic Door Locking and Unlocking System With Arduino. Components Required:- 1.Arduino MEGA 2.Keypad 4*4 3.Infrared Module (*2) 4.LCD Display 16*2 5.Power Supply(it can be between 5v to 12v max) (I have used 12v adapter for arduino and a 5v adapter for servo motor) 6.breadboard(optional) 7.box for Fitting the lcd and keypad 8.jumper wires **(I have used an external power supply for servo motor because, a rduino is not capable for supplying large current greater the 600mA and their are two many thing attached to arduino here which is continuously taking current through it, so it may happen that servo motor stop working due reduction in current) **(This has happened with me,the arduino keep on going reboot again and again)  Working of the lock:- Password for this is 1234. First if the door is closed and we enter the password 1234,it will print "Access Granted" on LCD and the door will open using the servo motor,I have

Arduino:How to make a RC car with arduino

Image
MULTI FEATURED ROBOT WITH ARDUINO This robot was mainly built for understanding Arduino and combining various projects of Arduino to form a Multi Featured Arduino Robot. And further, who doesn't want to have a pet robot? So I named it BLUE ROVIER 316. I could have bought a beautiful tracked chassis but making it from scratch teaches you more and gives you more pride after you have completed it. The robot is capable of understanding voice commands, answering simple questions, controlling as an RC car and even avoiding obstacles while moving. It is mainly controlled through an Android phone which is connected to it through Bluetooth. Based on Android features such as Google Voice Recognition and Tilt sensing, it can really behave like a cute, smart robot. I added BLUE in its name because it is mainly based on Bluetooth. It was actually my first Arduino project and I wanted it to be unique . If you like the project, please do vote for me in the Robotics Contest ! You w
