#write a micro python script to interface an LDR with GPIO14 of ESP32 todo the following:-
#1) Read the data from ldr and print the sam on shell window.
#2) calculate the ammount of valtage provided by ldr wrt to the change of light intnsity 
#3) control the led connected to GPIO2 of ESP32 
#4) control the brightness of the led wrt to intensity of light
