Escape Room Puzzle Tutorial - The "Fortune Teller's Crystal Ball"
HTML-код
- Опубликовано: 3 июл 2024
- In this video tutorial, I'll explain how to create a "Fortune Teller's Crystal Ball" escape room puzzle that uses the built-in touch input of an ESP32 microprocessor to detect when players place their hands on certain tarot cards. As they touch the cards, a crystal ball illuminates, using a MOSFET to gradually increase the current through a 12V LED lamp, and a sound effect plays through a serial MP3 player. When they touch the final card in the correct sequence, a relay is energised, releasing a maglock, allowing them to claim their prize.
I'll give a complete rundown of all the components I use, together with a detailed explanation of the wiring and code. More details and downloads for this tutorial, and all the other #EscapeRoom projects on this channel, can be found on my Patreon page at / playfultech

If you're using an Arduino, Raspberry Pi, or other microcontroller that doesn't have touch-enabled inputs, you can add them using a capacitive touch module such as a CAP1188, as demonstrated in this tutorial: • Arduino Capacitive Tou...

I have had a puzzle like this in mind, for a long time. Today it all fell into place. This contained just that extra I needed to be able to take it out of my mind and actually use it. Thanks again, Alastair!
I noticed in many of your puzzles that you trigger the maglock on the box immediately when the player completes the puzzle. For this one, I think it would be a bit better if you let the sound effect and lighting effect play, and then triggered the maglock. Maybe even after a slight pause.
That's a good idea - it would be a trivial change to the code to wait for a second or so until the ball had fully-illuminated before opening the lock - thanks for the suggestion!
I so enjoy your vids!! It helps my own home builds. Keep it up
Thanks again Alastair, i look forward to seeing how you altered analogwrite based on progression through the sequence
As always: love your work
Awh, thankyou - that's very kind of you to say so!
Freaking amazing!!
I was looking for this today and you just uploaded a video yesterday!
I guess you are psychic! 😂😂
Thanks again for a good video with explanations and covering review.
Just a note on power supply usage, you can use a diode to prevent flyback voltage. No need to add multiple power supplies for one prop/puzzle.
Great video and tutorial! Very thorough, I'm using your videos to teach my staff lol
Can you link the touch inputs ?
Also maybe a new video regarding touch inputs, how they work and how you can use them under multiple surfaces will be much appreciated.
Great work as always
I'm not using any "touch inputs" - it's just kitchen aluminium foil, which I've attached to pins on the ESP32.
There are some little cheap MOSFET boards often based around a D4148 MOSFET that have an optoisolator input so are very versatile on input voltage range and help protect your micro from wiring mistakes.
Oh nice - I'll check them out - thankyou for the tip!
That's sounds like a great idea, any suggestions on what I need to search for??
Just mosfet board with optoisolation?!?!
@@KrazeeKraftZ Dollatek D4184 MOSFET or just D4184 MOSFET board should find it.
@@mfx1ah yes, thanks found some
Awesome thanks, I might adapt that to work to release candy/toys at Halloween from my fortune tellers Hut.
The pictures could be whichever "prize" they want to receive.
Now I just need to work out how to get that item to magically appear in the "box"
Awesome idea, thanks
Sounds great!
Excellent video as always. I always learn a lot and get inspired to make more puzzles.
I want to do something similar however it’s direct 1 to 1
If you build game rooms or escape rooms, i wonder if you have any videos of the places where your games are in use, that could be fun to see if that is possible. Thanks for sharing your knowledge.
Yes, I build escape rooms for clients, but they typically don't want anyone filming inside the rooms for risk of spoiling the experience, let alone sharing those videos on RUclips!
Excellent video as always ! thx - I have a question : What is the thing under the aluminum foil (look like a bulb light) please ?
Here? ruclips.net/video/XTrP3Fah3Fk/видео.html It's just a screw and a washer, used to clamp the wire from the ESP32 onto the aluminium foil.
I am brand new to the Arduino culture and im so glad i found your channel! instant sub. i bought the new Arduino r4 wifi with an esp32 chip on it, would that work the same?
Thanks! I've not used the Arduino R4, but my understanding is that it should work the same - it's only when you come to do slightly more advanced things that involve timers and interrupts etc. where the architecture of the processor used on different boards starts to make a difference.
Hi! I've made a version off puzzle inspired in your code and hardware. In fact, I use exacty the same harware but I've replace the Mosfet and the Light with a Neopixel. All its going fine, but I have some problems playing de sound. It's running well, but sometimes when I power on the system the sound its not playing. I'm using a indenpendent power supply of 12V with ground conect to the ground of the circuit. I've try to use with a speaker and using the mini jack output, but the sound it's not going always. Only sometimes when i restart all de power supply. What you you thing its happening? Now it's happening almost always.... Thanks for your procets,. I 'll consider pay you for this code
Hello,
So I am trying to learn raspberry pi or Arduino. Me and my daughter do escape rooms weekly. I noticed you build your stuff in arduino instead of Pi. Is there a particular reason? Thanks
Do you not need a ground pin on the light bulb?
The bulb has a positive and a negative terminal, inserted into a circuit controlled by the MOSFET, as explained here: ruclips.net/video/XTrP3Fah3Fk/видео.html
