Re: My AC does not recognize if I send what I captured with IRremote
just try increasing the value until you stop getting more pulses in your capture.

Re: My AC does not recognize if I send what I captured with IRremote
FYI: you should be able to increase the IR current up to ~300mA for even better performance/range.
(assuming you are using a 5mm LED)

Re: My AC does not recognize if I send what I captured with IRremote
Great....However... - You will see that the buffer size of 100 may limit the size of signal received. - It appears that the ON/OFF signal is less than 100 in size. (=71) - That may not be the case for all the other signals. So if you receive issues with the other signal simply increase the size defi...

Re: My AC does not recognize if I send what I captured with IRremote
I will stay with the receiver part for now...
IR Receiver: That IR receiver you show is probably the worst you can get - but that is not likely your problem.
- I suggest you start again using the SimpleReceiver from the IRremote examples on Github. (You should only have to change the pin definition.)

Re: Constant current IR LED circuit
It could also be that the GPIO pin can not provide enough current to drive the transistor + the 2 diodes. Try taking out the diodes and see if it is any better. Maybe I should consider using a different transistor? The TIP120 is a bit too huge I guess. Agree just any jellybean NPN is OK (I usually u...

Re: Constant current IR LED circuit
As before put a resistor on the emitter of the transistor. It is likely the IR LED is blown because of effective short. resistor value: 3R (you can make this up by paralleling 3 or 4 10R resistors) This resistor is required.!!!!! You cannot put a yellow led in place because the current is much highe...

Re: AC Mitsubishi - use Arduino as IR remote - Raw data issues
I suggest you try to get it working first with a TV+remote to show that you understand & your hardware is working correctly. In the last capture above you should remove the '-' signs before compiling. If that does not work for you, please open a new thread and post more details (Sketch, transmit...

Re: Constant current IR LED circuit
post a circuit diagram of your setup -hand drawn is OK showing part numbers and values etc. Also show the voltage supply to the IR LED(s)
A photo would also be useful .
FYI: having no or too low value resistor 'could' blow the IR LED and/or transistor. See my previous post!

Re: Learnir V2 doesn`t work with analysir - Solved
Solved: Final solution was to upgrade to latest release, which supports the new BAUD rate for LearnIR.

Re: Learnir V2 doesn`t work with analysir
I just did a quick check and did not see any order from you for AnalysIR. If you did make an order for AnalysIR, please email the reference directly to support@....com (do not post here) The app you downloaded only runs in demo mode (before registration) and this would explain why it didnt work for ...
