THE ARDUINO HIGH STRIKER (HAU DEN LUKAS)

dear arduinos. )

i'm working friends since few month on following project: want connect arduino "on 1 side" (input pin 10) light barrier; "other side" connected remote control (out pin 2-9) dvd player. can find on dvd produced 8 chapters every second refers foregoing chapter (that have pairs of chapters: chapter 3 shows modified version of "clean" chapter 2; chapter 5 shows modified version of "clean" chapter 4 etc.). last not least, remote control used control 4 dvd-players of same brand. kind of high striker...as crosses light barrier.

concerning programming work function should control output , array make clear there's pairs of videos and, altogether, 6 pairs).

i can't find error in programming. moreover, arduino starts upload, then, nothing happens.

do see problem hide?

big thanks, stephan

       mystate = 0; // normal
     }
    break;

void startvideo(int pairs, int normalordistorted)
{
 digitalwrite(remotepins[pairs][normalordistorted],high);
 delay(500);
 digitalwrite(remotepins[pairs][normalordistorted],low);
 timer = millis();
} code tags added moderator

does refer 1 pin, or two:

pinmode ( remotepins [info][0], output);

my guess remotepins [ x ] [ y ] store 2 values, yes?

i didn't think pinmode assign 2 pins outputs @ 1 time.

maybe try instead set pins outputs:

for ( byte pins = 2; pins<10; pins = pins +1 )
{
pinmode ( pins, output );
}

also, maybe typo in question,
"i want connect arduino "on 1 side" (input pin 12) light barrier;"
but pin10 seems used vs pin12:

int lightbarrierin = 10;
