Very interesting. I was wondering how something like this works after looking at DFRobot's products. They use a single pin with buttons between the pin and ground, it must cycle somehow between output and input to get a reading of how much is going to ground. This is a handy method to do something similar with Arduino. Thanks!

Good question! You get a combination output of their resistance. The downside of this is that the more buttons you press, the less range you have to determine which buttons are pressed. This makes the probability of detecting the wrong button getting higher.
This is a great video. This means I can use one cable for my four button camera zoom control. I only have to add some resistors to my button-case. It is going to be cramped in there but I think I will manage. Here you can see my camera rig with 'home build Arduino zoom controller': th-cam.com/video/Q199zLxkKXs/w-d-xo.html If you watch the video you will notice that one handle has a little case with four buttons. This is meant to be able to zoom in and out in two speeds. It is designed for two cable but as I in principle only use the slowest zoom, the two extra buttons are not really needed and although I created the four buttons and extra wire possibility, I never adjusted the Arduino or software for handling 4 buttons. With your trick I am going to implement it after all. Thank you for the video.
I watched a bunch of tutorials on this topic, and this is by far the most helpful.
Glad you like it! Thanks! 😃
This video is brilliant, thank you so much for putting this up was totally lost when trying to figure out how this board!
Great to hear I could help 😃
Very helpful. I used this vid to create my own resistor-circuit with a joystick.
Great! Good luck with your project! 😃

Very nice Sir,,,
Thanks! 😃
Brilliant explanation! Thank you.
Thanks! 😃
can we use just one button instead four ones, and we use buttonpressedcount++ to know witch one was pressed?
Each button has its own resistance value so I guess this is not going to work.
I get a bunch of numbers scrolling around, but when I press buttons it works but I don't have 0 on the beginning
Sounds like a floating state. Perhaps a pull-down resistor is needed?
can the return be letters instead of numbers?
ex.
if (adValue > 300 && adValue < 500)
return UP;
You can return whatever you want, as long as the code is still valid 😃
what happens when 2+ buttons are pressed down at the same time?
Good question! You get a combination output of their resistance. The downside of this is that the more buttons you press, the less range you have to determine which buttons are pressed. This makes the probability of detecting the wrong button getting higher.
Can i make each bottom control relay
Sure, they just act as normal buttons 😃
