Hi, I'm new to arduino so I'm thinking I must be missing something simple as I am trying to control my air conditioner using an arduino Uno. The air conditioner is a Vaillant climoair and has the remote code 090 on the universal remotes. I have spent hours trying to make it work but have got comple…

I tried using a transistor to boost the power to the LED, now it shines brightly but still no response from the AC. I tried taking 10 samples of the same code and using the average values but again no response. I'm all out of ideas. J D

Hi INTP, Thank you for your reply. I do have the remote and did use the an IR receiver to capture the remote code, or at least try to. When I sent the captured code the A/C doesn't respond so I don't know if it hasn't captured it correctly or if it isn't sending it correctly. thanks J D

When you have your Arduino receiving code, are you seeing consistent codes in Serial Monitor? You need to see that a button reads the same each time, otherwise you're not set up with the right modulation protocol.

When receiving the codes using IRrecvDumpV2, the codes I get in the serial monitor always start Encoding : SANYO Code : FFFFFFFF (0 bits) Timing[193]: Then the long list of numbers is sort of consistent, for the same function/button, each number in the sequence is the same +-50. So for example t…

For starters, I don't think you are capturing the whole length of the IR signal. My AC IR signal is over 440 int length long, and according to your posts, your buffer size is only 193. The z3t0 library could never once sucessfully capture the full length of my AC IR remote codes. The only successful…

You're reading raw which you may not be getting the entire pattern. When you read for hex codes along a particular protocol, you will see Serial Monitor receive something like this, which is a mapping I did of a Vizio Smart TV Remote yesterday (I added back in the F's for effect): 20DFE21D FFFFFFF…

Hi Byork, Could you please explain a bit more on how you managed to get yours to work, for example which sketches or instructions on the analysir site you used. Did you have to change the frequency of irsend.sendRaw from the default 38? When I first used IRrecvDumpV2 with the buffer at the defaul…

JD, sure here's what I did. Both receiving and sending are tested on Uno and Nano. For receiving the signal, I am using the TSOP4838, connected to pin 2 according to the sketch. After pressing the button on your AC remote, you may need to wait up to 5 seconds for the code to appear in serial monito…

Byork, thank you so much. I now have it working. It looks like I was on the correct track but just needed to filter out the rubbish from the signal. My IR receiver, VS1838B, picks up all kinds of interference when using the analysir sketch. Putting it in a dark cardboard box and then putting that b…

Do you have the actual remote?

Using an IR receiver on the Arduino to get the codes would be a lot easier.
