Given your response to my answers I would question that.

I found an standalone photoresistor that came with the Arduino Kit i bought for several mounth ago. It worked perfectly and now i regret bying a bounch of the LDR modules i have.

But i'm learning on my way, and i did not break the bank, so i will survey :)
It's ok I think we all have plenty of "extra" parts and modules that may be good somewhere one day... :)

Agree, you can never have too many parts.

No, that means I don't care what you think of me.

I also don't have the time or the desire to discuss with you.

But i really think your nick maybe fits you well :)

Yes, some day they will be usefull.... maybe :)

Hi,
Did you google

ESP32 LDR

While Grumpy_Mike is often *** he is sometimes right on simple things. Such as here. You are using your module wrong. It has two outputs: you want to use the analog one marked as AO. You are using the "wrong" one (marked as DO). If you have time look at the module again, try to find a schematic and learn how it works. It is simple but useful circuit.

No, my module has no analog pin. Image i pasted earlier is an image i found on the internet i thought was the same, but is is'nt.

So Grumpy is right, bus the sametime not.....

My fault by the way...

:D

I wanna know what *** means

Perhaps the pin out will help... most of the pins are analog and digital.

I have seen it.

It does not helped me. It's much easyer to use an standalone LDR with two legs. Works as a charm, and much cheaper too :)

Bjerknes, perhaps there's a communication issue... Grumpy was pointing out that you can't use a digital pin to read analog data.  If it's working now then you have it on an analog pin.  Perhaps its a small language issue.

Maybe... but i uset the same pin. I just changed the LDR sensor and the second one worket fine. I'm sure it can be fixed with the right code etc. but it's much simplier to use an sensor that works out of the box :)
