I figured from the shots in your early videos about it that you probably had used the built-in pull up/down resistors in the Arduino. This was my very first Arduino project so it was a combined learning experience of Arduino, Air Manager, encoders, and a major refresher on my electronics education from too many years ago.

Unless they change the way the connections work, then yes, that should be all you need. And yes, the breadboard and all that was just me trying to collectively understand how the encoder works as well as general use of Arduino since this was my first time using both. Once you flash the Arduino with the program directly from Air Manager all you need are the direct wring connections between the Arduino board and the encoder node. The Arduino has internal resistors that the program enables. The software I used for my research and experimentation is the Arduino programming development tools. Again, that was just for my own education. You should not need to program anything manually. Just flash the Arduino directly from Air Manager to turn it into a functional knobster.

Hi Frank. I don't know all the new online tools to do schematics, so easier to draw by hand for now. Been a while since I drew one so it's not optimal, but it's laid out basically based on the physical layout on the breadboard. Also, I drew it from memory and referencing the video since I had already rewired for something else. Here ya go! raw.githubusercontent.com/peterlanoie/arduino/main/dual-rotary-encoder/WiringDiagram.jpg

@@peterlanoie Many thanks for your drawing!! Wow, this you call "not optimal"!? In my oppinion, your drawing ist perfect! :-) For the final use of/as Knobster (without the Diodes) i only have to remove the resitors/Diodes and connet the wires direct to GND, right? Greetings from Germany, Frank

@@frankbennewitz4922 I haven't gotten it working in air manager yet so my answer isn't proven, but yes, I think you need only remove the LEDs from pins D2 to D6 and move the knob connections onto those following the pinouts found on the knobster DIY page. (siminnovations.com/wiki/index.php?title=Knobster_DIY) Those have to match up. And that is what I'm trying at least for now. I'm guessing once you have those pins matched up and you "flash as knobster" from air manager, hopefully it will work. But I found nothing yet about whether you need to use external pull down resistors OR if their knobster code uses the pull up internal ones. If the latter, then removing the knob resistors would hopefully be enough. Russ Barlow's videos of his original knobster prototype did not show resistors that I could see. Viel Glück!

Hi again Frank. I finally got to testing out the knob and Nano using the Air Manager flashed Knobster firmware. Turns out you can remove everything but the knob itself. And you need to switch some things from how I had them in my tests. It seems that their program uses the pull-up internal resistors. So you just have to connect the ground pin to one side of the button and the two rotary "comm"s. Then attach the GPIO pins as listed on the wiki to the knob's connections (no resistors). I did this and it worked as expected. Happy Holidays!

​@@peterlanoie Hi Peter, many thanks for your tips! I draw the wireing too. Is my drawing correct? Here the Link: ibb.co/Rj2tytf

I took a close look at the dual encoder. It has a "1945" on the side and "LJV" on the end. Here are links I found (www.google.com/search?q=ljv+dual+encoder) for what appears to be the part: ljvraphael.blogspot.com/2016/08/ljv-dual-shaft-rotary-encoder-re08223ax.html ljv-05.bossgoo.com/metal-shaft-encoders/8mm-dual-shaft-rotary-encoder-with-potentiometer-push-on-switch-for-communication-equipment-10337201.html Hope this helps you find a supplier.

@@peterlanoie awesome thanks mate!

What did you think the fake Climate Crisis was going to do to everything? Make stuff cheaper? "You will have nothing and be happy" screams all the Euro Socialists in Unison, before they catch their next private flight to another Climate Change "crisis" symposium whose only result is more Commie/Fascism, them in charge of course.

The knobster is for use with air manager which itself connects to msfs.

How nice!
