It definitely needs to be "calibrated" (should be easy in the software) so that when it is evenly illuminated, all of the pixels in the screen display are even. With the LED light, they can be all 100% light. In the dark, they should all be 100% black... then, you should be able to resolve to at LEAST 256 shades of gray, from $00 to $FF for each pixel. It's "the worst camera" but a great project and demonstration of digital camera function. :)
I was just about to write same comment this definitely needs calibration and may be after calibration a few photo resistors will need to be replaced like the 3 or 4 that are too dark and the 2 upper right that are really too white.
That's so cool. Great project man. Then I was thinking about making a giant panel of photocells and a lens or magnifying glass to focus, I don't know, something like that
in a swipe going up to down, or left to right, depending o processor speed, you could sample the ldrs at 100/swipe speed. giving you like 800 x ?? pixels resolution. neat project.
Hi, nice project, can you share the code?

don't give up. Humanity is advancing with the efforts of investigative souls like you.
A black tube over each of the LDRs would prevent light leak, making it a bit more accurate
I think so, you win! Bad camera, awesome video!
Love it! It’s like pixel art, but pixel photography!
Harbor Freight flashlight FTW 😄
Interesting concept.

You should build a lens as well

put it in a pinhole cam thing..
