arduino ir control

There is a good Arduino IR library supporting both the send and receive features to control anything. I have already used it and you can setup a circuit very simple.

The problem I met is that this library support almost all the IR TV controller so I had to become a bit crazy setting the right protocol and reducing the range, due a too big program with most of the features absolutely unused. I suggest, after finding what is the protocol adopted by your device, to remove or at least comment the others.

You find the GitHub IRRemot code original library here: https://github.com/shirriff/Arduino-IRremote

I suggest you use it without any other code but with one of the provided examples to self-detect the communication protocol (try also with a TV IR remote controller to see what's happens). Then if you need specific help as you discover that your device uses a different protocol let me know. I have already done a modified library to control a product.

Thanks for your reply, there is only one problem which is that the helicopter requires a continuous stream data .. do you think that would be possible

Frankly I don't know in terms of hardware reliability but by the point of view of the software, I suggested just this solution because it is interrupt-driven. This means that as much as you kepp the signal frequence, as much you generate the IR data flow. Thus this is controlled by the hardware IRQ so your loop in theory will continue cycling with the control functions for autopilot.

I am not so sure that the hardware really saves so much time between an IRQ call and the other loop features, so it depends on the kind of other things the program will do.

The right approach in my vision is a interrupt driver IR driver integrated with the auto-pilot features taking in account when an immediate reactivity should be done. As a matter of fact, the auto-pilot process is a sort of macro that feeds continuously the IR controller, on request by the IR manager library. In this way, the IR IRQ control is not penalised.

What I suggest - as it sounds obvious and I have also experimented personally - is to avoid tasks like LCD display or serial updates in a production version of the program because these kind of tasks slowdown the entire program due to the low speed of the peripherals.

Basically, no

it could be possible with very limited range and indoors so the IR signal can bounce arround the room and improve chance of getting to the copter.

put it this way, how accurate is your TV remote control and how close do you need to be and in the right direction for it to work, this is no different
