The LEDs take 12V, so you can't plug those into an ESP/Arduino directly. You could use something like a low-side MOSFET switch to switch them, and feed them from a separate 12V power supply. You could use the same 12V supply to feed the ESP/Arduino, preferably with a step-down converter.
There is also an LDR light sensor on the board, which you can read out with an Arduino or ESP. You need to make a voltage divider consisting of the LDR and an appropriate series resistor (probably 10k or so would work), connect one end of the divider to GND and the other to 3.3V (ESP) or 5V (e.g. Arduino Uno) and the junction between the LDR and the series resistor to an analog input on your Arduino board.
You don't really need any library for any of this; anything you could possibly want to do with this can be done with digitalWrite, analogRead and maybe analogWrite if you want to PWM control the LEDs.
the doc seems to indicate that you drive this with 12V
So you need to drive those 12V through some sort of power transistor / mosfet from a PIN
EDIT: @rsmls was faster
Why do you need an Arduino?
What do you want to do with this light?
It is actually a IR source for a CCD cameras so it works after dark. It puts out a surprising amount of light. I have several that I use as fill, I simply connect 12V to 12V connector. As far as dimming the LEDs are a series parallel configuration so using PWM after you take the Light Sensor out of the circuit should solve it. You can short the output transistor so the LEDs are always on making the PWM setup simple.
Have you looked at the lights as the power is first turned on? I have several trail cameras with clear IR lLEDs and they start by producing visible RED light before they switch to IR. I discovered this because many animals are looking at the camera when their IR picture is taken. Then one night I triggered the camera and could see the instant the RED came on an then went away.
I need to remove the light sensor CDS ? The transistor too ? Or you want to mean I need to connect transistor output to my Arduino input ?
I suggest you use the transi
You don't you need to design an interface. What do you want to happen?
