The remote works perfectly! But my Apple react only every 5 sec.

I’ve checked the code, but nothing seems to be wrong.
Does anyone have this problem too?
Or is it the Apple?

Cool, so between Steve’s idea to use your computer’s line-in port and Josh’s idea to use an Arduino, everyone should be able to do the signal measurements even if they don’t have an oscilloscope. Thanks for the tips!

@riazap the truth is too hurtful ?

You truly are useless. Are you a libertarian or an objectivist? You certainly sound like someone brainwashed by Ayn Rand.

“I think the point of using an Arduino is that when this project gets boring, its easy to take the Arduino off to some other party.

but this mean you destroy you project, newer leaving working one, isn’t it better to grab new cheap chip from bag and leave working piece for future use ?

I’m not knocking PICs at all.
The PIC / MPLab and assorted compilers and certainly have more flexibility and power than Arduino. But for quick hobby projects that don’t require any optimization for manufacturability, battery life, speed, etc (read: actual engineering) it seems like the Arduino environment is ideal.

I think the point of using an Arduino is that when this project gets boring, its easy to take the Arduino off to some other party. Inevitably, the swiss-army knife factor comes into play here a bit ..

If you need something as huge as an arduino to create an IR remote, you fail at mc building. Look at the TVBGone – who needs an Arduino to pulse IR LEDs?

@riazap
Derangement Syndrome mean irrational belief despite all factual evidence(like false imaginary difficulties or unbelievable high cost) so professor, to which side this definition apply more ?

If not including a resistor in series with a current mode device isn’t wrong, then connecting two current mode devices in parallel certainly is.

If you wouldn’t do either of these things with power diodes, why is it that people think it’s okay with LE Diodes? Because they *look* like little globes? Is the need for current drive *really* that hard to understand?

I have examples of LED torches (flashlights) that depend entirely on the bulk resistance of the diodes in parallel and internal resistance of the battery in series – utterly bloody horrible “design”. Some LED’s do expire, and they make very poor use of the batteries. Yes, even manufacturers are getting away with such abominations, but they *are* abominations, not examples to emulate.

Adding a transistor stage will allow more current to be switched, but current setting resistors then become mandatory. IR LED’s in particular have the lowest cut-in voltage at 1.2 volts, and their V/I curve then rises almost vertically with a slope of amps per volt!

I don’t think a “reflector” is actually going to help much because most of the light is already being lensed into about a 30 degree forward cone. What does work is a bit more lensing to concentrate the energy into a narrower beam.

I’ve come up with a diagnosis for the thing people like therian are afflicted with. It’s A.D.S. (Arduino Derangement Syndrome).

@ladz
even pic ccs, which considered by many as worst language come with so much build in stuff that Arduino cant even dream about with all its shield

@ladz
what you talking about !?
in MPLAB you can real time debug, calculate each cycle time and use any language you like and most of them come with so large libraries that manual look like encyclopedia
