I saw somewhere on here (cant remember exactly where) that someone had set up a photo resistor to measure amibent light and dim the LCD's back light accordingly.
I really like this idea and I would like to try it out.
I use LCD's in parallel mode (not yet tried a serial one). I guess the code should be pretty simple - analogue read on the photo resistor, and set it to vary the voltage on a analogue output pin?
I'm unsure on the coding and what type (and where to look) photo-resistor to use?
Thanks in advance
