My goal is to make a circuit that can turn on my gas fireplace with a remote control. So I've got the infrared stuff working, but I need to get the relay switching figured out. So I've wired up CIRC-11 circuit, but I can't change the delay of switching (it defaults to 1000 milliseconds) the green and red lights just flip back and forth at the same rhythm. I also can't make the circuit do anything on any other pins besides 2, even though I change the code properly.
Any ideas?
Picture from Original Post - see Image Guide
I have no idea what CIRC-11 is - post a link to its datasheet.
Photos of wiring are generally impossible to figure out reliably. Make a pencil drawing of the connections and post a photo of the drawing.
Most important of all, post your code. And please use the code button </> so your code looks like this and is easy to copy to a text editor

It's from the arduino experimenter's kit: http://www.oomlout.com/oom.php/products/ardx/circ-11
And here's the code I'm using.
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
The circuit:
* LED connected from digital pin 13 to ground.
* Note: On most Arduino boards, there is already an LED on the board
connected to pin 13, so you don't need any extra components for this example.

int ledPin = 2; // Relay connected to digital pin 2 <-----Change this to pin 2
// The setup() method runs once, when the sketch starts
void setup() {
// initialize the digital pin as an output:
pinMode(ledPin, OUTPUT);
}
// the loop() method runs over and over again,
// as long as the Arduino has power
void loop()
{
digitalWrite(ledPin, HIGH); // set the LED on
delay(4000); // wait for a second
digitalWrite(ledPin, LOW); // set the LED off
delay(4000); // wait for a second
}

Have you accidentally posted the wrong program? That code is just the demo for blinking an LED
Also it does nothing for 1000 millisecs - both delay()s are for 4000 millisecs.
You should not use delay() in any serious program because an Arduino can do nothing during a delay() interval. Use millis() to manage timing. This is illustrated in Planning and Implementing a Program as well as general guidance about developing a program.
