For my school project I am creating a solar tracker. I'm just proving a theory and not actually making a large scalled version.
The tracking method that I decided on was using a light sensor. But LDR's decrease in resistance as light is lost. I'm going to have the LDR inside a small tube so that even if the sun (or in my case a small light) is slightly passed the tracker, the LDR's will have no resistance and therfor cause the tracker to move. However I need to reverse the LDR so as it increases in resistance as the light increases.
How would I go about this?
Sorry If I wrote it wrong because I probably confused myself.
Thanks,
Jason
