The information in this puzzle is just awesome Alastair. I was looking for info on how to trigger specific sounds from the audio device mapped on specific inputs and here it is. Needless to say the puzzle itself is very well thought and could be used in very creative ways. As an intro to a puzzle sequence for example.

Hey Alastair, I'm wondering what you named your Mp3 files so that the arduino knew which ones to play? Did you name them 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, etc.? also, how does the Patreon thing work? If I pay for it, do I get access to all of your videos or just one? I was thinking about getting involved in yours. You are very helpful and easy to understand. I also really like the stuff you do... Thanks, mark

OK I re-watched your video and now I understand what you named the sound files, but I am still curious about the Patreon thing that you are involved in...

Hi Mark, thanks for the comment and I'm really pleased you find the videos helpful! re: Patreon: basically, if you support me you'll be charged $10 each time I publish a new project (which I try to do once a month), and that will give you access to the code downloads and additional resources not just to that project, but to all my previous and future projects for as long as you stay subscribed. You can also message me to ask anything, and discuss with other Patrons who have made the same projects. So, right now, I think there's about 20 projects that you'd get access to. You can cancel anytime and, for anyone who doesn't want to or is unable to support me, I'll keep on putting up videos here on KZitem for free. Hope that explains, but please ask if you have any other questions!

Awesome tutorial! About how many buttons do you think would swing you in favor of using the multiplexer vs. going directly to the Arduino? Thanks!

That probably depends on exactly what model of "Arduino" you're using - e.g. a Mega has lots more available GPIO pins than an UNO/Nano, and a Wemos Mini has even fewer. I personally don't like using up *all* the available pins on a board. Even though there's nothing wrong with doing that, I always like to have one or two spare just in case there's functionality I want to add later (even just a simple pushbutton) without requiring a whole new resdesign.

Hi, fantastic video. Makes me want to make for/with my kids. I have a ton of questions but what would be simple (but useful) is to show us(ie “me”) how you solder the pins on the multiplexer, for example. It’s the nitty gritty stuff that is hard to do (for me). Maybe my electric cables aren’t suitable. What cables do you buy? Diameter and number of cores? Where do you buy them wires? What adaptor pins do you install between the cables and the boards? Thanks, keep on creating!

Thanks for the comment! Those wires aren't soldered actually - I used a crimping tool to make a custom harness for them, but that's a really great suggestion for a future video!

Hi, I got this code from patreon and it is working very well, but I have a problem and I was wondering if you could help me with it. I´m using usual bellbuttons and an opto coupler module before the multiplexer to connect 8 buttons to the Arduino. I know this is not necessary, but I thought it would be the easiest way without having to much expirience in coding and just to get it work. But now it seems like I somethimes get a little bit of bouncing on the buttons and even though the soundfile gets played correctly, the puzzle won´t be solved because one button got recognized twice. I there any advice how I can get this working by modifying the code? I would really appreciate help in this case. Thank you very much.

I love this puzzle it's so intuitive. I have question about the lock itself. I used a solenoid to hold a spring loaded cabinet closed. But due to the pressure (although very very minimal) the solenoid pin won't retract. I was thinking about using the particular electronic lock you have on this puzzle but since i don't have one i was wondering if you could solve me the question whether it would work on a spring loaded application.

I just can't get the dfPlayer to work. Everything else is doing what I want, but no sound, or even LED-light from the dfPlayer. I have tested it without the arduino and it worked. Hmm. Strange I think.

@@PlayfulTechnology Yes, I have build it up the same way as the shown example, only difference is: I'm using two 1kohm resistors instead of one 2kohm from dfPlayer RX to ground. I always get the "Initialising software serial interface to DFPlayer…....... Failure" . I'm pretty new to this, but I am thinking if the softwareSerial is the problem here. Just to test the rest of the setup, I have removed the return; in the void setup, just to be able to trigger the relay. And that part works fine.

@@arnebirger1 Hmm... well that sounds fine too. Can you try using a different pair of pins on the Arduino? i.e. change your sketch to say SoftwareSerial(9,10) and connect 9 to the DFPlayer Tx and 10 to the DFPlayer Rx?

While the wiring diagram has already been updated in the ressource files (Patreon), it might be good to point out here as well that the ground connection for the DFPlayer stereo output you see in this video at about kzitem.info/news/bejne/yYh4k2qkkICHgm0 is actually connected to the 5V rail. That said, very nice tutorial - as usual.
