Done Neb ...thank you so mush ...
this code fit to 1.3" OLED 128x64?

What do you guys think, is this LDR the correct one for this volume controller?
OPTOCOUPLER, 2KV, RESISTIVE O/P, Part # SILONEX NSL 32. | eBay
I need to use eBay, since Mouser doesn't have these and I don't want to order just the LDRs from Digikey and pay 18€ for delivery. Everything else from the BOM I can find from Mouser.
Nikosokey posted some OLED displays earlier, but those are quite small. I'm sure there are larger (2-3" diagonal) ones available too?

According to my understanding this should be compatible with zdr's OLED code?

That's quite expensive. Do you have rs components or farnell nearby?

Thanks for your answer Neb, but unfortunately there's no RS Components or Farnell local shops in Finland. So the NSL-32SR3 should also work in this circuit in stead of NSL-32SR2? I read earlier in this thread that you had some problems calibrating with it. Is that a major problem?

If this optocoupler is ok, I will just order these from eBay and be done with it.

There are problems with calibration, but you need to calibrate only once and never again, unless you change number of volume steps. It needs few runs to go through and that's it. But is seems sr3 behaves better in everyday use, ie no volume bump in the middle.

Hello.
Propably a noob question, but hey I'm a first time Arduino user. While I'm trying to send the code to the Arduino Nano from Arduino IDE 1.6.1, I get this error message: "firmware_LDR_v1.0_20160524.ino:20:31: fatal error: LiquidCrystal_I2C.h: No such file or directory"
I checked my Arduino libraries and I can see that I have this "LiquidCrystal_I2C.h" file in "C:\Program Files (x86)\Arduino\libraries\LiquidCrystal". What am I doing wrong? Please help.

Do you have the appropriate usb drivers installed? If yes, Go to Tools and there select the Port where your arduino is connected and try again.
D'oh! Of course I had the wrong COM port in the program. Now got the code into the Nano. Thanks again xcj999! Now I'm just waiting for the LCD 16x2 display to be delivered from China...
Yes, it's zdr's version of the board. I'm sure he will give you the price if you send him pm.
Something strange is going on with my 8V feed to Nano. When I connect the 8V supply (with both 12V supplies connected as well) I can hear some relays clicking and the power led on the Nano quite dimmly lits up. At first I can measure 7,9V from the Vin pin on the Nano, but only 0,8V from the 5V pins. After a while the LM7808 heats up a lot and the Vin pin measures below 3V and the resistors next to the LEDs on the Nano board heat up a lot as well. Then I have to unplug the power supply.
I wonder what's going on? Is my Arduino Nano somehow defective or have I made some mistake somewhere (quite possible)? Only the power supply was connected to the board during these initial tests.
