Timed Buttons Escape Room Puzzle Tutorial

This is a tutorial for an escape room puzzle using illuminated arcade buttons (the same ones I used at • Understanding ARCADE B... and • DIY Arduino Quiz Buzze... ).
The objective is simple - to make all the buttons light up at the same time - which releases a maglock and opens the door. However, when there are more buttons than there are players, and those buttons are positioned far apart (and/or in hard to reach places), it requires a bit more thought...
...the key is that each button stays lit for a certain duration (customisable in code) after they are released. Players must plan the correct order in which to press the buttons so that they can all be activated within the same time.

Thank you for posting these amazing and easy to follow vids! Back in 2021 i used your patreon for about 6 months to build puzzles throughout my house to turn it into an escape room style game. Was a blast sending my friends through it. Thank you for making that all possible!

Awh, that's great!

You could use this with your video about cctv footage. Where you have to flick switches in certain order. I can imagine this unlocking the old "wardrobe is actually a doorway to another room" thing in escape rooms.
Thanks again alastair, Im really grateful for your work

Thank you for the ferrule lesson! I was having that exact problem with stranded cable.

[@PlayfulTechnology]

Glad it helped!

Technically they're knock off Chinese "Wago" type connectors although annoyingly they make many useful types that Wago don't although Wago make nice panel mount holders for the official ones. Ferrules really aren't needed for lever/spring clamp terminals, only for screw terminals.

I have so much use of your ideas. So greatful 🙏.
Is it possible to buy a specific Sketch from you that you have made?
This Sketch was genius level short 😎 and powerful.

Hi, thanks for your comment - I don't really have a "shop" for individual sketches - I use Patreon because it's really convenient, but that's set up more for an ongoing subscription model. What sketch was it you were interested in? I'll see what I can sort out.

I’ll look through what project it was. I design my own hobby-level escape room for my friends at home and I just started dabble with Arduino. I have MScEE but it was a long time ago I programmed 🤣
