Mensen die op science park wonen, waar doen jullie boodschappen?

Ik kan er binnenkort wellicht gaan wonen, maar ik zie helemaal geen supermarkten in de buurt?
Nou ben ik als student wel een lege koelkast gewend, maar dit ziet er niet fraai uit. Hoe doen jullie dat?

need help with the code: I'm trying to connect 20 LDR's using two HC4067 16channel multiplexers

I'm using this LDR setup (without the LED), the resistor is a 10k resistor. I've tried vibe coding (I'm sorry). But the values i'm getting in the serial monitor keep getting weird, either all 20 channels give the same value, or they give noise.
I'm an art student and trying to build an interactive installation for the first time. I can't code, and i'm trying to learn this field.
I've tried this code found here: https://www.luisllamas.es/en/more-outputs-inputs-arduino-multiplexer-cd74hc4067/

but this does not seem to work, all values are kind of the same with this code, and my LDR doesn't seem to work anymore.
I understand this code is for one multiplexer, I'm also just testing one here.

Would be useful for a project I’m working on atm!

I’ve seen people program the position of nodes before, so I think it is possible.

Hi! I hope some of you could help me out. I have this chop with 20 channels. I want to make this grid 3D, and each individual cube to be customisable. When channel 1’s value is 1, the top left cube turns orange, and when channel 20’s value is 1, the bottom right cube is orange.

Later I also want to add other effects, like when a channel is 1, the cube moves or something, but I can do that later. For now I need to set it up correctly so every cube is customisable.
