Title: a non-polarized photoresistor?
Post by: sigurd on March 06, 2009, 05:03:45 PM

I decided to build the $50 robot as my first project.
I reccieved a photoresistor today, but it seems to be unpolarized. the whires are the same length, and there's no "+ / -" marked on it.
Will this anyhow affect my circut, and is it really a photoresistor at all?  :P

Like any resistor, photoresistors are not polarized.
