Valori fotoresistenze troppo variabili, cosa può essere?

-

salve tutti,
in un circuito con alcune fotoresistenze, sei servo motori e un port expander per controllare più led.

ho dei valori delle fotoresistenze che cambiano molto parità di luce.
es b schizza 1000 senza ragione, ma volte succede ad e così via...
cosa può determinare questo fenomeno?

qualche suggerimento?
grazie mille

es. valori parità di illuminazione, a, b, c sono fotoresistenze:

a: 647
b: 571
c:  647

a: 692
b: 570
c: 688

a: 688
b: 587
c: 689

a: 688
b: 634
c: 689

a: 687
b: 1010
c: 684

a: 646
b: 568
c: 645

a: 646
b: 687
c: 645

collegamento fotoresistenza:



- già provato staccare motori
- già provato togliere alimentazione al chip

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp
