Hi, in this project i want to help you with your Arduino, it is sometimes hard for beginners, to figure out what to put where in a code, so let me help you!
This is a small Instrucable, its just about a submission for arduino programming I made for beginners :)

Step 1:

So lets see, here is my submission for basic programs:

/*

Start, put description in here, it will help you and other, to find out what the code is about

*/

//insert Libraries here

//settings for librarys

//insert variables/constant here

//general other settings

void setup()   //first loop, runs 1x
{

   // serial definitions ( Serial.begin(); )

   //library settings #2

//define In/Outputs

//code which needs to run 1x

}

void loop() //main loop
{

// main code runs infty

}

/* End */

Just copy it into the Arduino programmer and start coding with it :)

Step 2: Finishing

Okay, i hope that helps you!
Me it helps alot, you can find an example code here:
