Check out the way to build boards using Fritzing! It is cool and free: http://www.fritzing.org

Here is my first circuit that I built using the Fritzing tool, and the VisualMicro Arduino code follows.

Arduino Code:

VisualMicro Code here, which looks like the “blink” example, and it is, with just a few small changes.

int led1 = 13;

void setup()
{

  /* add setup code here */
    // initialize the digital pin as an output.
    pinMode(led1, OUTPUT);
    }

void loop()
{

  /* add main program code here */
    digitalWrite(led1, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(1250); 
     digitalWrite(led1, LOW);    // turn the LED off by making the voltage LOW
    delay(250);      

}
