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)

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...

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.)

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...

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...

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...

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!

Solved: Final solution was to upgrade to latest release, which supports the new BAUD rate for LearnIR.

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 ...

In AnalysIR, Menu->File->Serial Port->Set BAud Rate->250000

The BAud Rate will then be remembered for future settings.

Make sure you have updated to the latest release....9445 or later. (Link was sent by email after purchase)
