Hi, I posted a bit back about turning my cctv ir sensors into adjustable and someone suggested a 100k trim pot, ive tried different values etc ad no joy.
Could someone help me as ive been in touch with Chinese suppliers and they either dont understand or help.
I have attached the photo of the board, i would like ideally to add a trimpot so i can adjust to its location and do the same on other cameras.
i did do a reading on the ldr and got the reading Full light 500 ohm and dark 1.3m I would have measured wrong and if so let me know the correct way.
thanks in advance.
