Newbie help needed

Ok so I am doing my first real project from scratch.

I am wanting to take 2 readings from the same sensor (digital) 5 seconds apart and compare the 2 readings and turn on a led if the value is higher or another on if it's lower.

Could I please get some help on how to do this.

Thanks in advance
Jason

int firstReading = readSensor ();
delay (5000);
int secondReading = readSensor ();
digitalWrite (firstLED, (firstReading > secondReading) ? HIGH : LOW);

Of course, there's a little bit of colouring-in to be done.

Thanks so much, I will let you know how I get on with the project :smiley:
