Alright guys. So I keep trying to find this, but I am about to give up. Using the Arduino Uno currently. I have setup the simple photoresistor.
I have set up the serial read so I can see what type of data is coming through. That way I know values to use for line following, IR sensors, etc.
As I play with the photo resistor bringing my hand closer and closer. The numbers go from 0(using flashlight) to about 800 - 900(complete darkness)
What is this value it is giving me?? Just some standard used by Arduino? Is it a round about voltage seen by the A0 port?
Does anyone have an idea?
Same thing when reading the IR range finder. When you read the values, what do the represent?
Thanks for the help
