Hi, I am using a photosensor as a variable resistor to vary the current according to light levels in my project. I am stumped on two problems and I was hoping a kind genius could help me out
1- I need to adjust the values to a much smaller range. According to my multimeter the photosensor has a resistance range from 200 Ohms (light) to 10K Ohms (dark), but I need a range of about 5-50 Ohms. Any quick and dirty way to tweak these values w/o hooking up 40 of these in parallel?
2- I would like to reverse the effect of the photosensor. So instead of increasing resistance with decreasing light, the resistance would decrease
with decreasing light.
Any tips would be greatly appreciated!
