Look at the Time library, TimesAlarms also if you need to run code at specific times.

@Bittsen
Look at response 24.
274  Using Arduino / General Electronics / Re: LED Input? on: April 27, 2014, 11:06:37 pm
Yes.
As long as you can garentee there is no other way for current to flow to the led circuit.

I'll have to get one of those boards.

You may be able to feed the Osc to an external CMOS gate and use it to buffer the signal.
You could bend the osc pin 90' so it makes no connection. If things still work then the osc is not used.

But does the fridge light go out when the door is closed?    smiley-wink
278  Using Arduino / Microcontrollers / Re: no external crystal 16Mhz after loading bootloader on: April 27, 2014, 09:41:33 pm
It may be a hardware difference between the devices.
I had a "some what" similar situation with 1284 low power operation vs full swing.

Show us your sketch and wiring.
280  Using Arduino / Project Guidance / Re: how can i start with my project? on: April 27, 2014, 08:26:57 pm
last semester i did voltage doubler it was easier than this

That's a big jump to this.
Settle on a product you want to make, get it approved, break it down into doable parts.

It is not surprising you don't see 16 MHz with the scope as it will effect the oscillator.
If blink works at the proper timing, then oscillator is OK.
282  Using Arduino / Project Guidance / Re: PIR code troubles, please help me on: April 27, 2014, 07:13:36 pm
Lose the ;
 if (digitalRead(pirPin) == HIGH);
Should be:
 if (digitalRead(pirPin) == HIGH)
{
// code here
}
283  Using Arduino / Project Guidance / Re: PIR code troubles, please help me on: April 27, 2014, 05:03:16 pm
What is wrong with these lines?
 if (digitalRead(pirPin) == HIGH);

 if (digitalRead(pirPin) == LOW);

What kind of programming/electronics experience do you have?
285  Using Arduino / Programming Questions / Re: Non-loop programming problem on: April 27, 2014, 04:29:38 pm
When you have done your thing a certain number of times make a variable true.
When your variable is true make a decision to stop doing the first thing then start doing the next thing.

Eat some food, eat some more eat some more.
Are you full?
Stop eating.
Rest some, rest some more, rest some more . . . . .
