In assembly language how do I write code to take input from a sensor and turns on a LED?
I'm writing an assembly program that will read information from a sensor that will detect whether its raining or not. the sensor will be the input and the LED will be the output indicating that its raining.
I have code written for 5 other weather conditions but right now I just want to figure out the most basic which is rain.

here's my code///////////////////////////I just want to know if I'm headed in the right direction, If not do you have any suggestions///////////////////
#include <>
;define equates here
count equ 0x00
sum equ 0x09

rainLed equ 4
rainSensor 10

dayOrNightLed equ 3
dayOrNightSensor 9

windLed equ 2
windSensor 8

snowLed equ 1
snowSensor 7

tempLed equ 0
tempSensor 6

fogLed equ 0
foqSensor 5

;start of program

org 0x0000 ; tells program to start at first location

BSF status, RP0 ; select bank 1
BCF status RP1

movlw b'11111000' ; make bank 5-10 inputs
movwf TRISA ;make bank 4-0 output

BCF status RP0 ;bit clear file
BCF status RP1

BTFSS PortA, rainSensor
BSF PortA,rainLed
is this part right so far?????????????????
