Conceive:

Initialization: set the pins of LED module and the photoresistor.
Loop:

① read the value of photoresistor and print it on Shell.

② Determine whether the value id less than 10000(the threshold can be changed according to needs).
- If the value is less than 10000, LED will be on.
- If the value equals or is greater than 10000, LED will go off.
