I completely understand the working principle of light dependent resistor. But there is one thing I am bothered about:
- Does the LDRs surface has to be equaly illuminated upon all its surface/upon all its photoresistive track? Or it doesn't really matter, if all of its photoresistive track is illuminated or only one part of the photoresistive track is illuminated?
- Are the LDRs values the same, if it gets illuminated upon all of its photoresistive track or if it gets illuminated upon only one part of photoresistive track?
