This is Arduino IDE(Integrated Development Enviroment)
Our aim in this short tutorial is to show you how to set up the Arduino IDE software to run a sketch.
If you have not Downloaded IDE then Click the Picture Below
Open the Arduino IDE software.
Click File> Examples > Basics> Blink
Click upload. Then observe your sketch blink the onboard LED.
If you dont want to go in blink Menu you can write Program below.
You Dont need to Attach any LED to 13 PIN because Arduino Uno Board has In bulit Led on 13 pin
pinMode(13,OUTPUT); // Pin initialization
digitalWrite(13,HIGH); // Turning On LED
delay(10000); // For 10000 ms = 10 sec
digitalWrite(13,LOW); //Turning OFF LED
delay(1000); // For 1000 ms = 1 sec
Update the code. Then upload the sketch, and watch the LED by change of delay.
Hurry you, made one program with Arduino.
