Good morning. My name is Jose, I know this post is very old but I would like to ask you something, this same project could be carried out with a KY-040 rotary encoder instead of linear potentiometers, thus avoiding breaks since customers force them and end up breaking the ends of the potentiometer. all the best.
Can you have multiple puzzles on a single Arduino that as you complete one puzzle the next puzzle become available to try and solve. Example - The puzzle Chris Ramsey just did on his channel. ruclips.net/video/1379SkZUx3M/видео.html
This is a really cool puzzle design! Do you mind telling me exactly what the LED strips are called with the data input? Most of the ones I come across don't include the data section. Cheers!
Hello and thank you once more for another high quality though easy to understand walkthrough. I've got a question if I may; It seems that you're powering the Arduino via USB. At about ruclips.net/video/wV6O_Kjl81U/видео.html you have a ground line from the external power for the leds connected to the Arduino. Why is that?
Yes, that's right. Voltage is the difference in electrical potential between two points. So, when we talk about 5V output from the Arduino, say, what that means is that there's a +5V difference in the voltage on that line *compared to ground*. If you connect other power supplies to the same circuit, you need to connect their grounds together so that they have a common reference point - the "zero" point from which all voltages can be expressed. Otherwise, a 12V supply will be measured relative to one "ground", while the 5V will be relative to a different "ground". Does that help explain?
Great teacher, hilarious ending! Amazing work!
That was a really interesting video, thanks.
(but, I do feel bad that I smiled as much as I did at the end of the video)

Such a great resource. Keep going...
You are a very good teacher. Thanks!

I need to make a clock for a carrier pigeon race to record their return from the race
I can’t find the right led strips (never mind I just have. They’re Neopixel”
"Neopixel" is a brand name - the generic name for the type of LEDs is actually WS2812.
This is a really cool puzzle design!

Nevermind, I managed to find them :)
What were they? All I can find are RGBV

This is fantastic
Why aren't you making new videos man??
Is the 5V supply to your lower breadboard missing in the diagram? The one going to the relay I mean.
Good spot - I've updated it! Cheers.
