ALtera DE2-115 GPIO input

Hi guys, I'm connecting a light sensor interface to a GPIO pin, the output of the sensor is high when light intensity is high and vice verse if the the light intensity is low, now I want to know, how...

I can't understand your question. You just said the sensor output is simply 1 or 0 depending on light intensity.

How can it become decimal or binary digits wen entering fpga?

Infact I understand your device is a simple on/off sensor switching at a fixed light threshold.

You'd have to manage a decimal or binary value only if you had a sensor capable to measure the actual ligh level.

But in that case the sensor would have a parallel or serial connection.
