Hi everybody,
This is a project to say hello for
Arduino :) It is a pretty common practice for beginners who is practicing for a new
language but when we say hello we are going to use a little bit different way
in this Arduino project :) This project's goal is blinking an LED every 2
seconds so Hello Arduino :)
What do we need to do this project
1 LED
1 Breadboard
1 Arduino Mega 2560 or other
Arduino boards
Arduino Software
If you want to loot at my all Arduino projects you can visit
http://technologylaboratory.blogspot.com/search/label/Arduino. They are not in English yet. I'm translating them too as this page so you should check them if you want to read my articles about Arduino. I recommend you my blog's Facebook page and Twitter account to follow news easly or you can add me your circle on Google plus.

If all components are ready we can
start.
The circuit is pretty easy to built
it. You can see the schematic view of the project one below. You need to attach
a resistor's one leg (its way is not important you can pick any leg) to pin 13
(actually pin number is not important neither you can choose any digital output
pin) and then you need to figure out led's positive leg to attach it to
breadboard. The LED's positive leg and resistors leg have to be to same row on
the breadboard after you attach the LED's negative leg to ground now it's ready
to blink the LED.
In the second step I'm going to
tell you the program that we are going to run it on Arduino.
Code:
/*

Project 1
Name : "Hello World"
*/
int ledPin = 13; // This
int variable to keep a
pin number that we attached an LED.
void setup(){ // this function works only once.
Arduino first run this function. In addition when you reset
// the Arduino it runs again.
pinMode(ledPin, OUTPUT); // we set the ledPin whose pin
number is 13 as an output. It means we
// can use this pin to sent
digital signal
}
void loop(){ // and the loop. it runs over
and over until you turn off the Arduino :)
digitalWrite(ledPin, HIGH);
// set the led pin as high
so turn it on
delay(2000); // (1000msec.=1sec.)
// wait for 2 seconds.
digitalWrite(ledPin, LOW);
// set the led pin as low so
turn it off
// high
and low mean the voltage level so when we control the voltage level it means we
can control // led's status as on or off
}
After you are done with all staff it is time to say hello so you need to
connect the Arduino board to your computer via USB port. after wait a few
seconds you need to click the verify and upload button. You can see the
screenshot from the Arduino software version 0022. It is the old one. There is
a new version but the compiling process is almost similar. Note: some libraries
and examples are not suitable for Arduino's new version so I recommend both of
the newest version one and version 0022 should be installed on your computer.
You can see some picture from the project. I'm going to share the video about this project after I upload it.
have a good one and see you at the next project :)
Did you see something wrong about my English ? Please let me know it and read this page.
