Arduino based LDR volume and source selection controller

Despite scepticism I'm still curious how it works in your case

My experience is that IR remote control does not work through the wood.

If you have a lot experience - please represent just one finished project in the wood case with IR remote. It can be proof of experience not just plain phrase on forum.

I just covered the IR sensor of my TV set with the thin (5~10mm) piece of wood and it did not work, as I expected... Does it count as a valid experiment?

You can show everybody your own finished project in the wood case. And after it we can discuss about curious situation..
I show my case as you can see in the previous post
And now your term ...

Is this not just due to leakage through the aperture cut out for the LCD display?

Chris, you right.

Chris, you right.

I expected so. I just noticed that zdr said the same thing in an earlier post:

IR normally does not pass through the wood. Maybe you have a parasitic passage of reflected beams through some other opening in your construction. Put a remote in completely closed wooden box and see if it works that way.

I expected so. I just noticed that zdr said the same thing in an earlier post:

As far I can see, opening in the case is closed by LCD panel, so how does the light go through, unless it's really a crappy fit?

 

[howarthcd]

Maybe the IR light is hitting the front of the LCD then being reflected internally and out through the sides of the glass to the inside of the case.

Could the LCD panel be transparent to the infra-red signal?

I didn't try with OLED but TFT works fine IR

So you modified the code to work with TFT?

I haven't tried remote functionality yet. I have other remotes that I cannot test, since debugging in OLED code doesn't work due to limited memory (I used up 99%).

Now this is interesting, it's a high res touch panel for as low as 5.2eur:

3 3V 240x320 2 4" SPI TFT LCD Touch Panel Serial Port Module With PBC ILI9341 | eBay

Unfortunatelly, it's dirt cheap for a reason.

Here is one I bought for one of my designs:

The viewing angles are pretty bad.

Here's the latest version, without zero volume bug

 

[howarthcd]

Last night I made a change to prevent repeat codes from other remotes from causing the unit to start changing the volume level. This would happen even if the volume control was varied several minutes before the repeat code from another remote was detected.

Let me know if you're interested, it's a small change to only allow repeat codes within 750ms of the last remote command.

I am interested in getting my no name remote to work in the first place Due to the size of the code with OLED, I am unable to run debug mode to read remote codes.

Just create a new sketch with just the remote handling code in and debug that. That's exactly what I did and it took about 10 mins in total.

Thanks. Took me quite a bit more than 10min, but I worked it out in the end.

This IR sensor is sensitive! I really did not need a hole, it picks up reflections from all directions. I can even cover all the openings on the front panel and it still works. I wish I knew this before I drilled the IR hole...

Thank you ZDR

I hope it will be good lesson for 'experienced' OlegSh .

 

[zdr]

This is really weird. I closed the box completely, closed the opening for both IR and OLED in front, and remote still works!
