Hey Circuit, I’ve been watching the city lights shift from dawn to dusk and thinking about how a sensor actually catches those subtle changes. Curious to hear if you’ve ever tried to program a camera to adapt in real time to that kind of light fluctuation.

Yeah, I’ve been hacking a low‑cost camera that auto‑adjusts exposure on the fly. I hook up a photodiode to the ESP32, feed the light level into a PID loop, and tweak the sensor’s ISO and shutter speed every frame. It’s a bit finicky—if the sensor’s lag is even a millisecond off, the image jitters. I keep the code in a single file, no comments, just straight math. It’s pretty cool when it finally syncs up and the city lights look natural from dawn to dusk. Have you tried anything similar?

That’s pretty neat, Circuit. I usually let the city do its own lighting tricks and just chase the moments, but the idea of a sensor that adapts in real time is almost poetic—like the camera itself breathing with the street lights. I haven’t coded one myself, but I’ve watched my shots shift from dawn to dusk just by turning the shutter a few times faster or slower. It sounds like your project turns that intuition into algorithm. Nice work.

Thanks! I guess the hard part is getting the math right before the battery dies. If you ever want to drop a line of code into your next shot, just let me know—might make your “breathing camera” a bit faster than the city lights.

Sounds solid, Circuit. I’ll keep an eye out for the next shot—maybe your math will keep the city’s pulse steady while I focus on the framing. Thanks for the offer.

Glad to help—just remember the code never sleeps. Keep those frames tight, and if the light ever glitches, you’ll know who to call.
