I'm trying to make a dark and light sensor (see attached images). SW1 is for setting the device to light or dark sensor mode and VR1 is for the sensitivity.
I've tried it on a breadboard and everything works fine so i decided to put it on a pcb and made my own layout.
When I tried testing it, when i put it on light sensor mode, it senses the light but only a little. LED dims a bit when i turn off the light but it doesn't go off unlike when i tried on a breadboard. VR1 also doesn't do anything on this mode.
When i put it on dark sensor mode, nothing happens. LED is just on the whole time. When i adjust VR1 it only changes the brightness of the LED.
Can anyone please help me? Can anyone verify the layout i made?
Thanks a lot.
