I am a totally newbie about my senor. It would be nice if I could get a little support/help with my problems.

I am trying to use this ASL board: link

It would be great if I can get some infos how the code on the nano sketch and fhem should look like, that I can can trigger/change functions from fhem to the nano/sketch and how can I get an info, when a pir changes a value of a varible in the sketch. Here is the existing code from the ardunio sktech:

#define MY_RADIO_NRF24
#define MY_REPEATER_FEATURE
#include <SPI.h>
#include <MySensors.h>
boolean sensor;
boolean MysenSor;


#define SHIFTPWM_NOSPI                            
const int ShiftPWM_dataPin = 6;                   //  Do not change!!!
const int ShiftPWM_clockPin = 7;                  //  Do not change!!!
const int ShiftPWM_latchPin = 8;                  //  Do not change!!!
#include <ShiftPWM.h>
const bool ShiftPWM_invertOutputs = false;         
const bool ShiftPWM_balanceLoad = false;         
#define sensorLight_PIN A0                        // Light sensor  Do not change!!!
#define sensorBottom_PIN A1                       // Bottom sensor Do not change!!!                     
#define sensorUpper_PIN A2                        // Upper sensor  Do not change!!!
unsigned char maxBrightness = 100;                // Here you set the number of brightness levels. Adjust(0-255)!!
unsigned char pwmFrequency = 75;                  // These values affect the load of ShiftPWM 
unsigned int numRegisters = 3;                    // Number of shift registers Do not change!!!
unsigned int numOutputs = numRegisters * 8;
unsigned int numRGBLeds = numRegisters * 8 / 3;
boolean sensorUpperActive;
boolean sensorBottomActive;
int numberOfstairs=6;                           // Setup Number of Your stairs. Adjust up to 24 !!!!
int pause=30000;                                    // Setup delay ON/OFF  Adjust!!!

 }

It would be great if I can some help/support :-)
