So I am building a line follower robot, I have seen various tutorials with parts lists, Its just in our works we have quite a few LDR's lying around.
Thought If I posted a spec of these you would be able to tell me if they are useful, if not I could just order more.
The line will be white on a dark background and apparently I need to use these and some infared LED's, we have lots of red LED's but apparently they have to be infared
anyway heres the LDR's
