K8055 and a Light Sensor

Kits PC Related Projects

Greetings,

I recently purchased a K8055 USB board.
My main intention was to use a light sensor to detect precise values, what those values come from is of no real importance.
I figured while reading through the manual, and looking at the numbers on the potentiometers, that the light sensor should produce a maximum resistance of 100K ohm in total darkness, and operate under 5 volts.
I would like to know if my forementioned statement is correct?

If so, is it possible for me to attach a potentiometer between the sensor and the analog input to tune the incoming signal?

Also, I read it takes an average of 20ms to process every command sent to the card.
So, if I were to spam the card every 20ms asking for the value of the first analog input, this should produce no problems?

Thanks in advance,
-Bed.
