void loop () decleration problem

hi guys,

1.      if define digitalwrite(in1,high) , want make low in loop. possible?

2.    if possible whenever void loop() function executes once lets have set digitalwrite(in1,low), happen if loop starts again set in1 high defined in setup or writes low because declared low in first execution?

3.    or program executes void setup() function once while loop executed continiosly? may impossible set pin different state if declared in setup function  :~

1: yes
2: remain low
3: yes.

take @ "main.cpp" in arduino's ide files - you'll see how works:

code: [select]


    setup();

    (;;) {
        loop();
        if (serialeventrun) serialeventrun();
    }
