I just purchased an Arduino UNO from Radio Shack. I am reading your book "Getting Started with Arduino". I downloaded the software to my PC Windows 7 Ultimate. I created the sketch as indicated in the book Page 31 but the led does not change on and off rate. I changed the on and off to 2 on 6 off but it blinks the same.
HELP! Manny from Puerto Rico
//This my first sketch on Arduono
//This sketch will light a LED on and off
//Every eight seconds.
const int LED = 13; // LEDE connected to
//digital pin 13
digitalWrite(LED,HIGH); //Turns the led on
delay(2000); //Waits for 2 seconds
digitalWrite(LED,LOW); //Turns the LED OFF
