[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying ...

b: The on-off ratios (the ratio of conductivity with/without pseudo-sunlight) of the photoresistor devices. The higher the on-off ratio, the better the performance of the photoresistor.

His testing revealed that the photoresistor was better able to detect ... tool when it comes time to start tweaking shutter mechanisms. If this project has brought out the shutterbug in you ...
