When PC0 sends a high level, it is charged with essentially 5V plus the capacitance. After a few milliseconds, the voltage of the capacitor reaches almost 5V. If the program changes the I/O port so that the port simply monitors the voltage, the capacitance discharges through the photoresistor. As the capacitor discharges through the photoresistor, the voltage decays, and as the charge is lost, the voltage drops. The time it takes for PC0 to sense the voltage drop to 1.4V depends on the amount of current flow capacity provided by the photoresistor to block the capacitance. If the resistance value of the photoresistor is large due to weak external light, the capacitor needs to be discharged for a longer time, otherwise, the capacitor can lose charge quickly. The measured decay time can be used to characterize the resistance of the photoresistor. The resistance value in turn indicates the intensity of light detected by the photoresistor.
